Maxim Integrated MAX5712AUT T

Description
The MAX5712 is a low-power, 12-bit digital-to-analog converter (DAC) with a small footprint. It operates from a single 2.7V to 5.5V supply and features an on-chip precision output amplifier that provides rail-to-rail output swing. With a supply current of only 85μA at 3V, the MAX5712 is ideal for portable battery-operated equipment.
The MAX5712 utilizes a 3-wire serial interface compatible with SPI/QSPI/MICROWIRE and DSP-interface standards. All logic inputs are CMOS-logic compatible and buffered with Schmitt triggers for direct interfacing to optocouplers. It incorporates a power-on reset (POR) circuit that ensures the DAC begins in a zero-volt-state upon power-up. A power-down mode that reduces current consumption to 0.3μA can be initiated through a software command.
The MAX5712 is available in a small 6-pin SOT23 package.
