This device is targeted for optical micro-electromechanical systems. The output voltage range is programmable via the REF_IN pin. The output range is 0 V to 50 V when REF_IN = 1 V, and 0 V to 200 V when REF_IN = 4 V. Each amplifier can source 550 µA, which is ideal for the deflection and control of optical MEMS mirrors. The selected digital-to-analog converter (DAC) register is written to via the 3-wire interface. The serial interface operates at clock rates of up to 30 MHz and is compatible with DSP and microcontroller interface standards. The device is operated with AVCC = 4.75 V to 5.25 V, DVCC = 2.7 V to 5.25 V, V+ = ...
