The MAX5712EUT+T is a low power, 12bit, rail to rail voltage output serial DAC in 6 pin SOT-23 package. The MAX5712 on-chip precision output amplifier provides rail to rail output swing. Drawing only 85μA supply current at +3V, the MAX5712 is ideally suited for portable battery-operated equipment. The MAX5712 utilizes a 3-wire serial-interface that is compatible with SPI/QSPI/MICROWIRE and DSP-interface standards. All logic inputs are CMOS-logic compatible and buffered with schmitt triggers to allow direct interfacing to optocouplers. The MAX5712 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 may be initiated through a software command.
