32-Channel, 14-Bit DAC with Full-Scale Output Voltage Programmable from 50 V to 200 V www.DataSheet4U.com Preliminary Technical Data FEATURES High integration: 32-channel, 14-bit DAC with integrated, high voltage output amplifier Guaranteed monotonic Housed in 15 × 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 DSP-/microcontroller-compatible serial interface Channel update rate: 1.2 MHz Asynchronous RESET facility Temperature range: –10°C to +85°C AD5535 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. APPLICATIONS Optical micro-electromechanical systems (M...
