MAX5711

19-2195; Rev 1; 10/04 MAX5711 10-Bit, Low-Power, Rail-to-Rail Voltage-Output Serial DAC in SOT23 General Description 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-...
