AD7792/AD7793 is a 3-channel, low noise, low power, 16-/24-bit ∑-Δ ADC with on-chip In-Amp and reference.
The AD7792 and AD7793 are low‑power, low‑noise analog‑to‑digital converters with 16‑bit (AD7792) and 24‑bit (AD7793) resolution. They include an on‑chip instrumentation amplifier, band‑gap reference, programmable gain, and programmable current sources, making them suitable for precision measurement applications such as thermocouples, RTDs, and gas analysis.
The devices operate from a 2.7 V to 5.25 V supply, consume about 400 µA typical current, and function over a temperature range of –40 °C to +105 °C. Output data rates are software‑programmable from 4.17 Hz to 470 Hz, and the parts are offered in a 16‑lead TSSOP package.
