FEATURES GENERAL DESCRIPTION
High integration
32-channel, 14-bit DAC with integrated high voltage
output amplifier
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.
Guaranteed monotonic
Housed in 15 mm × 15 mm CSP_BGA package
Full-scale output voltage
Programmable from 50 V to 200 V via reference input
700 μA drive capability
Integrated silicon diode for temperature monitoring
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.
