This is an AD5755 datasheet. It 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, voltage and current output DAC that operates from a –26.4 V to +33 V supply and supports dynamic power control for thermal management. It offers 16‑bit resolution, programmable offset and gain, on‑chip diagnostics, and an on‑chip reference with ±10 ppm/°C stability.
The device uses a versatile 3‑wire serial interface compatible with SPI, QSPI, MICROWIRE, DSP and microcontroller standards, and includes optional CRC‑8 error checking and a watchdog timer. Detailed specifications, functional block diagrams and pin descriptions are provided throughout the document.

The AD5755 uses a 3‑wire serial interface compatible with standard SPI, QSPI, MICROWIRE, DSP and microcontroller interfaces, with optional CRC‑8 error checking and a watchdog timer.
Dynamic power control minimizes package power dissipation by regulating the voltage on the output driver from 7.4 V to 29.5 V using an on‑chip DC‑to‑DC boost converter.
