... DAC with Full-Scale Output Voltage Programmable from 200 V 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 REF_IN pin. The output range when REF_IN = 1 V, and 200 V when REF_IN = 4 V. Each amplifier can source 700 μ ...

... These bits are used to write a 14-bit word into the addressed DAC register. Figure 2 is the timing diagram for a serial write to the AD5535. The serial interface works with both a continuous and a discon- tinuous serial clock. The first falling edge of SYNC resets the serial clock counter to ensure that the correct number of bits are shifted into the serial shift register ...
