AD5735 is a quad-channel, 12-bit, serial input, 4 mA to 20 mA and voltage output DAC with dynamic power control
The AD5735 DAC provides four independent channels that can output either voltage or current. It operates from a power‑supply range of –26.4 V to +33 V and features on‑chip dynamic power control to minimize dissipation. The device uses a 3‑wire serial interface compatible with SPI, QSPI, Microwire and other standards, with optional CRC‑8 error checking and a watchdog timer.
The datasheet includes detailed specifications for voltage and current output ranges, resolution, accuracy, timing, and layout guidelines. It also describes companion products, functional block diagrams, and recommended PCB design practices for low‑noise operation and galvanic isolation.

The AD5735 provides 12‑bit resolution for both voltage and current output modes.
It supports multiple voltage ranges including 0‑5 V, 0‑10 V, –5 to +5 V, –10 to +10 V, 0‑6 V, 0‑12 V, –6 to +6 V, and –12 to +12 V.
The device can output currents from 0 mA up to 24 mA, with selectable sub‑ranges of 0‑20 mA and 4‑20 mA.
The AD5735 operates with a supply voltage between –26.4 V and +33 V.
