AD5546/AD5556 are 16-bit/14-bit multiplying DACs with four-quadrant resistors, current output, and parallel input. AD5546/AD5556 can be configured as four-quadrant multipliers for a variety of applications, including automatic test equipment, instrumentation, digital waveform generators, and digitally controlled calibration.
The AD5546 and AD5556 are precision 16‑/14‑bit multiplying DACs with four‑quadrant resistor networks, offering low‑power current‑output operation from a single 2.7 V to 5.5 V supply. They provide ±10 V output ranges, built‑in feedback and resistor networks, and are packaged in a compact TSSOP‑28.
Typical applications include automatic test equipment, instrumentation, digitally controlled calibration, and waveform generation. The datasheet includes functional block diagrams, electrical characteristics, timing diagrams, pin descriptions, and ordering information.
