The MAX5712 utilizes a 3-wire serial-interface that is compatible with SPITM/QSPITM/MICROWIRETM 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 0.3A may be initiated through a software command. The MAX5712 is available in a small 6-pin SOT23 package. For dual and quad 12-bit versions, see the MAX5722 and MAX5742 data sheets. For single, dual, and quad 10-bit versions, see the MAX5711, MAX5721 and MAX5741 data sheets. The MAX5712 is specified over the automotive temperature range of -40C to +125C.
