MAX5523EUA+

The MAX5523EUA+ is a dual, ultra low power, 10bit voltage output digital to analogue converter (DAC) in 8 pin µMAX package. This device offers rail to rail buffered voltage output. It operates from 1.8V to 5.5V supply and consume less than 5μA making the devices suitable for low power and low voltage applications. A shutdown mode reduces overall current including the reference input current to 0.18μA. Upon power-up, the MAX5523 outputs are driven to zero scale providing additional safety for applications that drive valves or for other transducers that need to be off during power-up. The zero scale outputs enable glitch free power-up. The MAX5523 contains a precision internal reference and provides a buffered external reference output with unity gain DAC outputs. It is used in automatic trimming and calibration in factory or field, programmable voltage and current sources, remote data conversion and monitoring, chemical sensor cell, bias for gas monitors and programmable LCD bias.
