Analog Devices AD7190 Datasheet
The AD7190 is a low‑noise, 24‑bit sigma‑delta analog‑to‑digital converter designed for high‑precision measurement applications such as weigh scales, strain‑gauge transducers, pressure and temperature sensing, chromatography, and data‑acquisition systems. It offers up to 22.5 noise‑free bits, programmable gain from 1 to 128, and selectable output data rates from 4.7 Hz to 4.8 kHz.
The device operates from a 5 V analog supply and a 2.7‑5.25 V digital supply, consuming about 6 mA. It is available in a 24‑lead TSSOP package and includes features such as an on‑chip clock, simultaneous 50 Hz/60 Hz rejection, four general‑purpose digital outputs, and multiple input configurations (2 differential or 4 pseudo‑differential channels).
