The MAX5711 is a small footprint, low-power, 10-bit digital- to-analog converter (DAC) that operates from a single +2.7V to +5.5V supply. The MAX5711 on-chip precision output amplifier provides rail-to-rail output swing. Drawing an 85µA supply current at 3V, the MAX5711 is ideally suited to portable battery-operated equipment.The MAX5711 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 to allow direct interfacing to optocouplers. The MAX5711 incorporates a poweron reset (POR) circuit that ensures that 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.The MAX5711 is available in a small 6-pin SOT23 package. For dual and quad 10-bit versions, see the MAX5721 and MAX5741 data sheets. For single, dual, and quad 12-bit versions, see the MAX5712, MAX5722, and MAX5742 data sheets. The MAX5711 is specified over the automotive temperature range of -40°C to +125°C.ApplicationsAutomatic Tuning (VCO)Battery-Powered ApplicationsGain and Offset AdjustmentPower Amplifier ControlProcess-Control I/O BoardsVCO Control
