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.
The selected digital-to-analog converter (DAC) register is written
to via the 3-wire interface. The serial interface operates at clock
rates of up to 30 MHz and is compatible with DSP and micro-
controller interface standards.
The device is operated with AVCC = 4.75 V to 5.25 V, DVCC =
2.7 V to 5.25 V, V+ = 4.75 V to 5.25 V, and VPP of up to 225 V.
REF_IN is buffered internally on the AD5535B and should be
driven from a stable reference source.
