APPLICATIONS
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 REFIN pin. Output range is 0 V to 50 V
with REFIN = 1 V and is 0 V to 200 V with REFIN = 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 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, VPP
= 210 V. REF_IN is buffered internally on the AD5535 and
should be driven from a stable reference source.
