Part details & applications

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.

APPLICATIONS

Optical microelectromechanical systems (MEMS)
Optical crosspoint switches
Micropositioning applications using piezoelectric actuators
Level setting in automotive test and measurement
