The MAXQ7667 smart system-on-a-chip (SoC) provides a time-of-flight ultrasonic distance-measuring solution. The device is optimized for applications involving large distance measurement with weak input signals or multiple target identification. The MAXQ7667 features high signal-to-noise ratio achieved by combining flexible electronics with the intelligence necessary to optimize each function as environmental and target conditions change.An integrated burst signal generator and echo reception components process ultrasonic signals between 25kHz and 100kHz. Echo reception components include a programmable gain low-noise amplifier (LNA), a 16-bit sigma-delta ADC to digitize the received echo signals, and digital signal processing (DSP). DSP limits noise with a bandpass filter, and creates an echo envelope through demodulation and lowpass filtering. Input referred noise is a low 0.7µVRMS. A programmable phase-locked loop (PLL) frequency synthesizer supplies the reference frequency for the burst generator and the clock for the echo receiver's digital filter. An embedded 16-bit MAXQ20 microcontroller (µC) controls all the preceding functions.The µC optimizes the burst frequency and reception frequency for each transmission at any temperature. The MAXQ7667 achieves smart sensing by monitoring the echo signals and then actively changing the transmitted and received parameters to obtain optimum results. Digital filtering and burst synthesis do not require CPU intervention. This leaves all the CPU power available for echo optimization, communication, diagnostics, and additional signal processing.The MAXQ7667 operates with three different power supply voltages: +5V, +3.3V, and +2.5V. Two internal linear regulators allow operation from a single +5V supply when three external power supplies are not available. Alternatively, the MAXQ7667 can control an external pass transistor to allow operation from a single supply voltage of +8V to +65V or more, depending on the external component tolerance.

The DS4560 is a self-contained hot-plug switch intended to be used on +12V power buses to limit through current and to control the power-up output-voltage ramp. The device contains an on-board 25mΩ n-channel power MOSFET that is actively closed-loop controlled to ensure that an adjustable current limit is not exceeded. The maximum allowable current through the device is determined by an external resistor connected to the ILIM pin.The DS4560 also contains the ability to control the power-up output-voltage ramp. A capacitor connected to the VRAMP pin sets the desired voltage ramp rate. The output voltage is unconditionally clamped to keep input overvoltage stresses from harming the load. The DS4560 also contains an adjustable power-up timer. A capacitor connected to the TIMER pin determines how long after power-on reset the DS4560 should wait before starting to apply power to the load. The TIMER pin can also be driven with a digital logic output to create a device-enable function.The DS4560 contains an on-board temperature sensor with hysteresis. If operating conditions cause the device to exceed an internal thermal limit, the DS4560 either unconditionally shuts down and latches off awaiting a power-on reset (DS4560S-LO), or it waits until the device has cooled by the hysteresis amount and then restarts (DS4560S-AR).ApplicationsBase StationsInfiniBand™PCI/PCI Express®RAID/Hard DrivesServers/Routers

Each DAC can also operate with an external reference, which sets the DAC full-scale output to the external reference voltage.These DACs communicate via an SPI/MICROWIRE-compatible 3-wire serial interface which operates at clock rates up to 50MHz. Hardware clear (CLR) and asynchronous DAC update (LDAC) pins are available in the MSOP package. The LTC2636 incorporates a power-on reset circuit. Options are available for reset to zero-scale or reset to mid-scale in internal reference mode, or reset to mid-scale in external reference mode after power-up.Applications Mobile Communications Process Control and Industrial Automation Automatic Test Equipment Portable Equipment Automotive Optical Networking

The LTC2636 is a family of octal 12-, 10-, and 8-bit voltage-output DACs with an integrated, high-accuracy, low-drift 10ppm/°C reference in 14-lead DFN and 16-lead MSOP packages.
