The MAX531/MAX538/MAX539 are low-power, voltage- output, 12-bit digital-to-analog converters (DACs) specified for single +5V power-supply operation. The MAX531 can also be operated with ±5V supplies. The MAX538/MAX539 draw only 140µA, and the MAX531 (with internal reference) draws only 260µA. The MAX538/MAX539 come in 8-pin DIP and SO packages, while the MAX531 comes in 14-pin DIP and SO packages. All parts have been trimmed for offset voltage, gain, and linearity, so no further adjustment is necessary.The MAX538's buffer is fixed at a gain of +1 and the MAX539's buffer at a gain of +2. The MAX531's internal op amp may be configured for a gain of +1 or +2, as well as for unipolar or bipolar output voltages. The MAX531 can also be used as a four-quadrant multiplier without external resistors or op amps. For parallel data inputs, see the MAX530 data sheet.ApplicationsBattery-Operated/Remote Industrial ControlsBattery-Powered Test InstrumentsDigital Gain and Offset ControlGeneral PurposeMachine- and Motion-Control Devices

The MAX5392 dual, 256-tap, volatile, low-voltage, linear taper digital potentiometer offers three end-to-end resistance values of 10kΩ, 50kΩ, and 100kΩ. Operating from a single +1.7V to +5.5V power supply, the device provides a low, 35ppm/°C end-to-end temperature coefficient. The device features an I²C interface.The small package size, low supply operating voltage, low supply current, and automotive temperature range of the MAX5392 makes the device uniquely suited for the portable consumer market, battery-backup industrial applications, and the automotive market.The MAX5392 is specified over the automotive -40°C to +125°C temperature range and is available in a 16-pin TSSOP package.ApplicationsAdjustable Voltage References/Linear RegulatorsAutomotive ElectronicsLow-Voltage Battery ApplicationsMechanical Potentiometer ReplacementOffset and Gain ControlPortable Electronics
