32通道14位DAC的滿量程輸出電壓可編程從50V至200V的ad5535b數(shù)據(jù)表

　　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 550 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 microcontroller 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.
