The AD45335 is targeted for optical micro-electromechanical systems. The output voltage range is programmable through 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. REF_IN is buffered internally on the AD45335 and must be driven from a stable reference source. The selected digital-to-analog converter (DAC) register is written to using the 3-wire interface. The serial peripheral interface (SPI) operates at clock rates of up to 30 MHz. Figure 1.
