The AD7792BRUZ is a 3-channel, low noise, low power, 16-bit Σ-Δ Analogue-to-digital Converter with on-chip in-amp and reference. The on-chip, low noise instrumentation amplifier means that signals of small amplitude can be interfaced directly to the Analogue-to-digital Converter. With a gain setting of 64, the rms noise is 40nV when the update rate equals 4.17Hz. The devices contain a precision low noise, low drift internal band gap reference and can accept an external differential reference. Other on-chip features include programmable excitation current sources, burnout currents and a bias voltage generator. The bias voltage generator sets the common-mode voltage of a channel to AVDD/2.
