GENERAL DESCRIPTION
The AD5535 is a 32-channel, 14-bit DAC 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 700 μA, which is ideal for the
deflection and control of optical MEMS mirrors.
The selected 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 microcontroller 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, V+ = 4.75 V to 5.25 V,
and VPP = 210 V. REF_IN is buffered internally on the AD5535
and should be driven from a stable reference source.
