Analog Devices AD7785 Datasheet
The AD7785 is a complete analog front‑end for high‑precision measurement applications. It integrates a low‑noise 20‑bit Σ‑Δ ADC, three differential inputs, an on‑chip instrumentation amplifier, programmable gain, and a band‑gap reference. The device operates from a 2.7 V to 5.25 V supply and supports update rates from 4.17 Hz to 470 Hz.
Typical applications include thermocouple, RTD, thermistor, gas analysis, industrial process control, and portable instrumentation. The datasheet provides detailed specifications, pin descriptions, timing diagrams, and guidance on grounding, layout, and calibration.
