The OP249 is a high speed, precision dual JFET op amp, similar to the popular single op amp. The OP249 outperforms available dual amplifiers by providing superior speed with excellent dc performance. Ultrahigh open-loop gain (1 kV/mV minimum), low offset voltage, and superb gain linearity makes the OP249 the industry’s first true precision, dual high speed amplifier.With a slew rate of 22 V/μs typical and a fast settling time of less than 1.2 μs maximum to 0.01%, the OP249 is an ideal choice for high speed bipolar DAC and ADC applications. The excellent dc performance of the OP249 allows the full accuracy of high resolution CMOS DACs to be realized. Symmetrical slew rate, even when driving large load, such as, 600 Ω or 200 pF of capacitance and ultralow distortion, make the OP249 ideal for professional audio applications, active filters, high speed integrators, servo systems, and buffer amplifiers.Applications Output amplifier for fast DACs Signal processing Instrumentation amplifiers Fast sample-and-holds Active filters Low distortion audio amplifiers Input buffer for ADCs Servo controllers

The OP467 is a quad, high speed, precision operational amplifier. It offers the performance of a high speed op amp combined with the advantages of a precision op amp in a single package. The OP467 is an ideal choice for applications where, traditionally, more than one op amp was used to achieve this level of speed and precision.The internal compensation of the OP467 ensures stable unity-gain operation, and it can drive large capacitive loads without oscillation. With a gain bandwidth product of 28 MHz driving a 30 pF load, output slew rate is 170 V/μs, and settling time to 0.01% in less than 200 ns, the OP467 provides excellent dynamic accuracy in high speed data acquisition systems. The channel-to-channel separation is typically 60 dB at 10 MHz.The dc performance of the OP467 includes less than 0.5 mV of offset, a voltage noise density below 6 nV/√Hz, and a total supply current under 10 mA. The common-mode rejection ratio (CMRR) is typically 85 dB. The power supply rejection ratio (PSRR) is typically 107 dB. PSRR is maintained to better than 40 dB with input frequencies as high as 1 MHz. The low offset and drift plus high speed and low noise make the OP467 usable in applications such as high speed detectors and instrumentation.The OP467 is specified for operation from ±5 V to ±15 V over the extended industrial temperature range (−40°C to +85°C) and is available in a 14-lead PDIP, a 14-lead CERDIP, a 16-lead SOIC, and a 20-terminal LCC.Contact your local sales office for the MIL-STD-883 data sheet and availability.Applications High speed image display drivers High frequency active filters Fast instrumentation amplifiers High speed detectors Integrators Photo diode preamps

The AD1582/AD1583/AD1584/AD1585 are low cost, low power, low dropout, precision band gap references. These designs are available as 3-terminal (series) devices and are packaged in the compact SOT-23, 3-lead surface-mount package. The versatility of these references makes them ideal for use in battery-powered 3 V or 5 V systems where there can be wide variations in supply voltage and a need to minimize power dissipation.The superior accuracy and temperature stability of the AD1582/AD1583/AD1584/AD1585 result from the precise matching and thermal tracking of on-chip components. Patented temperature drift curvature correction design techniques minimize the nonlinearities in the voltage output temperature characteristic.The AD1582/AD1583/AD1584/AD1585 series mode devices source or sink up to 5 mA of load current and operate efficiently with only 200 mV of required headroom supply. These parts draw a maximum 70 μA of quiescent current with only a 1.0 μA/V variation with supply voltage. The advantage of these designs over conventional shunt devices is extraordinary. Valuable supply current is no longer wasted through an input series resistor, and maximum power efficiency is achieved at all input voltage levels.The AD1582/AD1583/AD1584/AD1585 are available in two grades, A and B, and are provided in a tiny footprint, the SOT-23.

The AD5253 / AD5254 are quad-channel, I2C, nonvolatile memory, digitally controlled potentiometers with 64/256 positions, respectively. These devices perform the same electronic adjustment functions as mechanical potentiometers, trimmers, and variable resistors.The parts’ versatile programmability allows multiple modes of operation, including read/write access in the RDAC and EEMEM registers, increment/decrement of resistance, resistance changes in ±6 dB scales, wiper setting readback, and extra EEMEM for storing user-defined information, such as memory data for other components, look-up table, or system identification information.The AD5253 / AD5254 allow the host I2C controllers to write any of the 64-/256-step wiper settings in the RDAC registers and store them in the EEMEM. Once the settings are stored, they are restored automatically to the RDAC registers at system power-on; the settings can also be restored dynamically.The AD5253 / AD5254 provide additional increment, decrement, +6 dB step change, and –6 dB step change in synchronous or asynchronous channel update mode. The increment and decrement functions allow stepwise linear adjustments, with a ± 6 dB step change equivalent to doubling or halving the RDAC wiper setting. These functions are useful for steep-slope, nonlinear adjustments, such as white LED brightness and audio volume control.The AD5253 / AD5254 have a patented resistance-tolerance storing function that allows the user to access the EEMEM and obtain the absolute end-to-end resistance values of the RDACs for precision applications.The AD5253 / AD5254 are available in TSSOP-20 packages in 1 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ options. All parts are guaranteed to operate over the –40°C to +105°C extended industrial temperature range.
