MAX5721EUA+

The MAX5721EUA+ is a 10bit, low power, dual, voltage output DAC with serial interface in 8 pin µMAX package. The wide supply voltage range and 112μA supply current accommodate low power 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 SPI, QSPI, MICROWIRE and DSP-compatible serial interface saves board space and reduces the complexity of opto and transformer isolated applications. The MAX5721 on-chip power-on reset (POR) circuit resets the DAC outputs to zero and loads the output with a 100Kohm 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 power-down reduces supply current to less than 0.3μA.
