The MAX5721 dual 10-bit, low-power, buffered voltageoutput, digital-to-analog converter (DAC) is packaged in a space-saving 8-pin MAX package (5mm 3mm). The wide supply voltage range of +2.7V to +5.5V and 112A supply current accommodate lowpower and low-voltage applications. DAC outputs employ on-chip precision output amplifiers that swing rail-to-rail. The MAX5721's reference input accepts a voltage range from 0 to VDD. In power-down the reference input is high impedance, further reducing the system's total power consumption. The 20MHz, 3-wire SPITM, QSPITM, MICROWIRETM and DSP-compatible serial interface saves board space and reduces the complexity of opto- and transformerisolated applications. The MAX5721 on-chip power-on reset (POR) circuit resets the DAC outputs to zero and loads the output with a 100k resistor to ground. This provides additional safety for applications that drive valves or other transducers that need to be off on power-up. The MAX5721's software-controlled powerdown reduces supply current to less than 0.3A and provides software-selectable output loads (1k, 100k, or high impedance) while in power-down. The MAX5721 is specified over the -40C to +125C automotive temperature range
