GENERAL DESCRIPTION
The AD5535B 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. Each amplifier can source 550 µA, which is ideal for the deflection and control of optical MEMS mirrors.
