Analog Devices AD7739 Datasheet
The AD7739 is a high‑precision, high‑throughput analog‑to‑digital converter featuring eight single‑ended or four fully‑differential input channels. It offers 24‑bit resolution with no missing codes, selectable input ranges (+0.625 V, +1.25 V, +2.5 V), and a 3‑wire serial interface compatible with SPI, QSPI, Microwire and DSP.
The device operates from a single 5 V analog supply, supports temperatures from –40 °C to +105 °C, and dissipates as little as 85 mW in normal mode. Detailed specifications, timing diagrams, pin configurations, and calibration procedures are provided for designers of industrial instrumentation and multiplexed measurement systems.
