Analog Devices AD7794/AD7795 Datasheet
The AD7794 and AD7795 are low‑power, low‑noise analog‑to‑digital converters offering up to 24‑bit resolution (AD7794) or 16‑bit (AD7795). They integrate a precision band‑gap reference, programmable gain instrumentation amplifier, on‑chip bias generator, and a low‑side power switch for sensor power‑down.
The devices operate from a 2.7 V to 5.25 V supply, support SPI/QSPI/MICROWIRE interfaces, and provide selectable update rates from 4.17 Hz to 470 Hz. Typical applications include temperature, pressure, weigh‑scale, strain‑gage, and other high‑precision sensor measurements.
