MAXIM INTEGRATED PRODUCTS  MAX5522EUA+  数模转换器, 超低功率, 电压输出, 10 bit, 串行, 1.8V 至 5.5V, µMAX, 8 引脚

The 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 MAX5522 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 device accepts an external reference input and provides unity gain outputs. The MAX5522 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.
