The AD5757 is a quad, current output DAC that operates with a power supply range from 10.8 V to 33 V. It features dynamic power control and HART network connectivity.
The AD5757 is a quad, 16‑bit current‑output DAC that operates from a 10.8 V to 33 V supply. It features dynamic power control to minimize dissipation, on‑chip reference, diagnostics, and a versatile 3‑wire serial interface compatible with SPI, QSPI, Microwire, DSP and microcontroller standards. Each channel includes a CHART pin for HART signal coupling.
Designed for process control, actuator control, PLCs and HART‑networked industrial applications, the device offers selectable output ranges (0‑24 mA, 0‑20 mA, 4‑20 mA), low offset and gain errors, and programmable offset and gain. Detailed specifications, timing diagrams, and programming sequences are provided for integration into embedded systems.
