The AD5535 is a high-integration 32-channel, 14-bit DAC with an integrated 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. Integrated silicon diode for temperature monitoring.
The AD5535 from Analog Devices is a high‑integration, 32‑channel, 14‑bit digital‑to‑analog converter designed for optical MEMS, cross‑point switches, piezoelectric actuators and automotive test equipment. It offers a programmable full‑scale output from 50 V to 200 V using a reference input (REF_IN) of 1 V‑4 V.
The device operates from dual supplies (AVcc 4.75‑5.25 V, DVcc 2.7‑5.25 V) and provides a 1.2 MHz channel‑update rate with a 3‑wire serial interface that supports up to 30 MHz clock speeds. It includes integrated temperature‑monitoring diodes and ESD protection for reliable high‑voltage operation.
