MAX5741 19-2123 Rev 4 5/08 10-Bit, Low-Power, Quad, Voltage-Output DAC with Serial Interface General Description Features The MAX5741 quad, 10-bit, low-power, buffered volt- Ultra-Low Power Consumption age-output, digital-to-analog converter (DAC) is pack- 229A at V = +3.6V DD aged in a space-saving 10-pin MAX package (5mm 3mm). The wide supply voltage range of +2.7V to 271A at V = +5.5V DD +5.5V and 229A supply current accommodates low- Wide +2.7V to +5.5V Single-Supply Range power and low-voltage applications. DAC outputs employ on-chip precision output amplifiers that swing 10-Pin MAX Package rail-to-rail. The MAX5741s reference input accepts a voltage range from 0 to V . In power-down the refer- 0.3A Power-Down Current DD ence input is high impedance, further reducing the sys- Guaranteed 10-Bit Monotonicity (1LSB DNL) tems total power consumption. Safe Power-Up Reset to Zero Volts at DAC Output The 20MHz, 3-wire SPI, QSPI, MICROWIRE and DSP-compatible serial interface saves board space and Three Software-Selectable Power-Down reduces the complexity of opto- and transformer-isolated Impedances (100k, 1k , Hi-Z) applications. The MAX5741 on-chip power-on reset Fast 20MHz, 3-Wire SPI, QSPI, and MICROWIRE- (POR) circuit resets the DAC outputs to zero and loads the output with a 100k resistor to ground. This provides Compatible Serial Interface additional safety for applications that drive valves or other Rail-to-Rail Output Buffer Amplifiers transducers that need to be off on power-up. The Schmitt-Triggered Logic Inputs for Direct MAX5741s software controlled power-down reduces supply current to less than 1A and provides software- Interfacing to Optocouplers selectable output loads (1k, 100k, or high impedance) Wide -40C to +125C Operating Temperature while in power-down.
