Analog Devices AD7709 Datasheet Handbook
The AD7709 is a 16‑bit sigma‑delta ADC with programmable gain, switchable current sources, and on‑chip rail‑to‑rail input buffers. It supports single‑supply operation at 3 V or 5 V and offers simultaneous 50 Hz and 60 Hz line‑frequency rejection. The device includes a 3‑wire serial interface compatible with SPI, QSPI, Microwire, and DSP protocols.
The document provides a functional block diagram, detailed specifications, timing characteristics, pin configuration, and application notes such as sensor measurement, temperature, pressure, and 4‑20 mA loop instrumentation. Ordering information, absolute maximum ratings, and ESD handling guidelines are also included.
