The AD5755 is a quad, 16-bit, serial input, 4 mA to 20 mA and voltage output DAC with dynamic power control
The AD5755 is a quad‑channel DAC that provides both voltage and current outputs with 16‑bit resolution. It operates from a wide power‑supply range (‑26.4 V to +33 V) and includes on‑chip dynamic power control to reduce thermal dissipation. The device uses a versatile 3‑wire serial interface compatible with SPI, QSPI, Microwire, DSP and microcontroller standards, and offers optional CRC‑8 error checking and a watchdog timer.
Typical applications include process control, actuator control, and PLCs. The datasheet details functional block diagrams, pin configurations, timing characteristics, and extensive performance specifications such as output voltage ranges, current ranges, accuracy, and noise figures.
