GENERAL DESCRIPTION

The AD45335 is a 32-channel, 14-bit denseDAC? with an on-chip

high voltage output amplifier. 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.
