MAX5711 19-2195 Rev 1 10/04 10-Bit, Low-Power, Rail-to-Rail Voltage-Output Serial DAC in SOT23 General Description Features The MAX5711 is a small footprint, low-power, 10-bit digi- Wide -40C to +125C Operating Temperature tal-to-analog converter (DAC) that operates from a single Range +2.7V to +5.5V supply. The MAX5711 on-chip precision Low 85A Supply Current output amplifier provides rail-to-rail output swing. Drawing an 85A supply current at 3V, the MAX5711 is Ultra Low 0.3A Power-Down Supply Current ideally suited to portable battery-operated equipment. Single +2.7V to +5.5V Supply Voltage The MAX5711 utilizes a 3-wire serial interface compatible with SPI/QSPI/MICROWIRE and DSP-interface Fast 20MHz 3-Wire SPI/QSPI/MICROWIRE and standards. All logic inputs are CMOS-logic compatible DSP-Compatible Serial Interface and buffered with Schmitt triggers to allow direct interfac- Schmitt-Triggered Inputs for Direct Interfacing to ing to optocouplers. The MAX5711 incorporates a power- Optocouplers on reset (POR) circuit that ensures that the DAC begins in a zero-volt-state upon power-up. A power-down mode Rail-to-Rail Output Buffer that reduces current consumption to 0.3A may be initiat- Power-On Reset to Zero Volts ed through a software command. Three Software-Selectable Power-Down Output The MAX5711 is available in a small 6-pin SOT23 pack- age. For dual and quad 10-bit versions, see the MAX5721 Impedances (100k , 1k , Hi-Z) and MAX5741 data sheets. For single, dual, and quad Tiny 6-Pin SOT23 Package 12-bit versions, see the MAX5712, MAX5722, and MAX5742 data sheets. The MAX5711 is specified over the automotive temperature range of -40C to +125C.
