The AD5306 / AD5316 / AD5326 are quad 8-, 10-, and 12-bit buffered voltage output DACs, in a 16-lead TSSOP package, that operate from a single 2.5 V to 5.5 V supply, consuming 500 µA at 3 V. Their on-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/μs. A 2-wire serial interface that operates at clock rates up to 400 kHz is used. This interface is SMBus-compatible at VDD

The AD539 is a low distortion analog multiplier having two identical signal channels (Y1 and Y2), with a common X input providing linear control of gain. Excellent ac characteristics up to video frequencies and a −3 dB bandwidth of over 60 MHz are provided. Although intended primarily for applications where speed is important, the circuit exhibits good static accuracy in computational applications. Scaling is accurately determined by a band-gap voltage reference and all critical parameters are laser-trimmed during manufacture.The full bandwidth can be realized over most of the gain range using the AD539 with simple resistive loads of up to 100 Ω. Output voltage is restricted to a few hundred millivolts under these conditions. The two channels provide flexibility. In single-channel applications, they can be used in parallel to double the output current, in series to achieve a square-law gain function with a control range of over 100 dB, or differentially to reduce distortion. Alternatively, they can be used independently, as in audio stereo applications, with low crosstalk between channels. Voltage-controlled filters and oscillators using the state-variable approach are easily designed, taking advantage of the dual channels and common control. The AD539 can also be configured as a divider with signal bandwidths up to 15 MHz.Power consumption is only 135 mW using the recommended ±5 V supplies. The AD539 is available in three versions: the J and K grades are specified for 0 to 70°C operation and S grade is guaranteed over the extended range of −55°C to +125°C. The J and K grades are available in either a hermetic ceramic SBDIP (D-16) or a low cost PDIP (N-16), whereas the S grade is available in ceramic SBDIP (D-16) or LCC (E-20-1). The S grade is available in MIL-STD-883 and Standard Military Drawing (DESC) Number 5962-8980901EA versions.APPLICATIONS Precise high bandwidth AGC and VCA systems Voltage-controlled filters Video signal processing High speed analog division Automatic signal-leveling Square-law gain/loss control

The AD5426 / AD5432 / AD5443 are CMOS 8-, 10-, and 12-bit current output digital-to-analog converters (DACs), respectively. These devices operate from a 2.5 V to 5.5 V power supply, making them suitable for battery-powered applications and many other applications.These DACs use a double buffered, 3-wire serial interface that is compatible with SPI, QSPI™, MICROWIRE™, and most DSP interface standards. In addition, a serial data out pin (SDO) allows for daisy-chaining when multiple packages are used. Data readback allows the user to read the contents of the DAC register via the SDO pin. On power-up, the internal shift register and latches are filled with 0s and the DAC outputs are at zero scale.As a result of manufacturing on a CMOS submicron process, the parts offer excellent 4-quadrant multiplication characteristics with large signal multiplying bandwidths of 10 MHz. The applied external reference input voltage, VREF, determines the full-scale output current. An integrated feedback resistor, RFB, provides temperature tracking and full-scale voltage output when combined with an external current to voltage precision amplifier.The AD5426 / AD5432 / AD5443 DACs are available in small, 10-lead MSOP packages.The EVAL-AD5443SDZ / EVAL-AD5446SDZ / EVAL-AD5453SDZ evaluation board is available for evaluating DAC performance.

The AD580 is a three-terminal, low cost, temperature compensated, bandgap voltage reference which provides a fixed 2.5 V output for inputs between 4.5 V and 30 V. A unique combination of advanced circuit design and laser-wafer trimmed thin-film resistors provide the AD580 with an initial tolerance of ±0.4%, a temperature stability of better than 10 ppm/°C and long-term stability of better than 250µV. In addition, the low quiescent current drain of 1.5 mA max offers a clear advantage over classical Zener techniques.The AD580 is recommended as a stable reference for all 8-, 10- and 12-bit D-to-A converters that require an external reference. In addition, the wide input range of the AD580 allows operation with 5 volt logic supplies making the AD580 ideal for digital panel meter applications or whenever only a single logic power supply is available. The AD580J, K, L and M are specified for operation over the 0°C to +70°C temperature range; the AD580S, T and U are specified for operation over the extended temperature range of -55°C to +125°C.

The AD581 is a 3-pin, temperature compensated, monolithic, band gap voltage reference that provides a precise 10.00 V output from an unregulated input level ranging from 12 V to 30 V. Laser wafer trimming (LWT) is used to trim both the initial error at +25°C as well as the temperature coefficient, resulting in high precision performance previously available only in expensive hybrids or oven regulated modules. The 5 mV initial error tolerance and 5 ppm/°C guaranteed temperature coefficient of the AD581L is available in a monolithic voltage reference.The band gap circuit design used in the AD581 offers several advantages over classical Zener breakdown diode techniques. Most important, no external components are required to achieve full accuracy and significant stability to low power systems. In addition, total supply current to the device, including the output buffer amplifier (which can supply up to 10 mA) is typically 750 μA. The long-term stability of the band gap design is equivalent to selected Zener reference diodes.The AD581 is recommended for use as a reference for 8-, 10- or 12-bit digital-to-analog converters (DACs) that require an external precision reference. The device is also ideal for all types of analog-to-digital converters (ADCs) up to 14-bit accuracy, either successive approximation or integrating designs, and can generally offer better performance than that provided by standard self-contained references.The AD581J, K, and L are specified for operation from 0°C to +70°C; the AD581S, T, and U are specified for the -55°C to +125°C range. All grades are packaged in a hermetically sealed three-terminal TO-5 metal can.PRODUCT HIGHLIGHTS Laser trimming of both initial accuracy and temperature coefficient results in very low errors over temperature without the use of external components. The AD581L has a maximum deviation from 10.000 V of ±7.25 mV from 0°C to 70°C, whereas the AD581U guarantees ±15 mV maximum total error without external trims from −55°C to +125°C. Because the laser trimming is done on the wafer prior to separation into individual chips, the AD581 is extremely valuable to hybrid designers for its ease of use, lack of required external trims, and inherent high performance. The AD581 can also be operated in a 2-pin Zener mode to provide a precision −10 V reference with just one external resistor to the unregulated supply. The performance in this mode is nearly equal to that of the standard 3-pin configuration. Advanced circuit design using the band gap concept allows the AD581 to give full performance with an unregulated input voltage down to 13 V. With an external resistor, the device operates with a supply as low as 11.4 V. 5. The AD581 is available in versions compliant with MILSTD-883. Refer to the military datasheet for detailed specifications.

The AD625 is a precision instrumentation amplifier specifically designed to fulfill two major areas of application: 1) Circuits requiring nonstandard gains (i.e., gains not easily achievable with devices such as the AD524 and AD624). 2) Circuits requiring a low cost, precision software programmable gain amplifier.For low noise, high CMRR, and low drift the AD625JN is the most cost effective instrumentation amplifier solution available. An additional three resistors allow the user to set any gain from 1 to 10,000. The error contribution of the AD625JN is less than 0.05% gain error and under 5 ppm/°C gain TC; performance limitations are primarily determined by the external resistors. Common-mode rejection is independent of the feedback resistor matching.A software programmable gain amplifier (SPGA) can be configured with the addition of a CMOS multiplexer (or other switch network), and a suitable resistor network. Because the ON resistance of the switches is removed from the signal path, an AD625 based SPGA will deliver 12-bit precision, and can be programmed for any set of gains between 1 and 10,000, with completely user selected gain steps.For the highest precision the AD625C offers an input offset voltage drift of less than 0.25 µV/°C, output offset drift below 15 µV/°C, and a maximum nonlinearity of 0.001% at G = 1. All grades exhibit excellent ac performance; a 25 MHz gain bandwidth product, 5 V/µs slew rate and 15 µs settling time.The AD625 is available in three accuracy grades (A, B, C) for industrial (-40°C to +85°C) temperature range, two grades (J, K) for commercial (0°C to +70°C) temperature range, and one (S) grade rated over the extended (-55°C to +125°C) temperature range.
