The MAX5741 quad, 10-bit, low-power, buffered voltage-output, digital-to-analog converter (DAC) is packaged in a space-saving 10-pin MAX package (5mm 3mm). The wide supply voltage range of +2.7V to +5.5V and 229A supply current accommodates lowpower and low-voltage applications. DAC outputs employ on-chip precision output amplifiers that swing rail-to-rail. The MAX5741'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 transformer-isolated applications. The MAX5741 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 MAX5741's software controlled power-down reduces supply current to less than 0.1A and provides softwareselectable output loads (1k, 100k, or high impedance) while in power-down. The MAX5741 is specified over the -40C to +125C extended temperature range and available in a 10-pin MAX package
