Analog Devices AD7734 Datasheet
The AD7734 high‑precision, high‑throughput analog‑to‑digital converter offers four single‑ended inputs, selectable input ranges up to +10 V, and over‑voltage tolerance up to +16.5 V. It operates from a single 5 V analog supply and supports SPI, QSPI, Microwire, and DSP‑compatible serial interfaces with Schmitt‑triggered logic inputs.
Key specifications include 24‑bit resolution with no missing codes, conversion rates up to 12.2 kHz (chopping enabled), and operation over an industrial temperature range of –40 °C to +105 °C. The device is supplied in a 28‑lead TSSOP package and is intended for PLC/DCS, multiplexing, process control, and industrial instrumentation applications.
