The AD5780 is an 18‑bit voltage‑output DAC with ±1 LSB INL, low‑noise performance and a wide ±16.5 V supply range.
The AD5780 is a true 18‑bit voltage‑output DAC that provides ±1 LSB integral non‑linearity (INL) and a low output‑noise density of 8 nV/√Hz. It operates from a bipolar supply up to ±16.5 V and includes an integrated precision reference buffer. The device supports a high‑speed 35 MHz serial interface compatible with SPI, QSPI, Microwire and DSP protocols.
Typical applications include medical instrumentation, test and measurement, industrial control, aerospace data‑acquisition systems, and power‑control circuits. An evaluation board and software tools are supplied to simplify design integration and performance verification.
