The AD45335 is a 32-channel, 14-bit denseDAC^® with an on-chip high voltage output amplifier. 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. REF_IN is buffered internally on the AD45335 and should be driven from a stable reference source.

The selected digital-to-analog converter (DAC) register is written to via the 3-wire interface. The SPI operates at clock rates of up to 30 MHz.
