AD5535B:  32-Channel, 14-Bit DAC with Full-Scale Output Voltage Programmable from 50 V to 200 V

Product Details

Product Status:Recommended for New Designs

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 700 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.
