The AD7794CRUZ is a 6-channel low noise, low power 24-bit sigma-delta Analog-to-digital Converter (ADC) with on-chip in-amp and reference for high precision measurement applications. The on-chip low noise instrumentation amplifier means that signals of small amplitude can be interfaced directly to the ADC. Each device contains a precision low noise, low drift internal band gap reference and can also accept up to two external differential references. Other on-chip features include programmable excitation current sources, burnout currents and a bias voltage generator that is used to set the common-mode voltage of a channel to AVDD/2. The low-side power switch can be used to power down bridge sensors between conversions, minimizing the system power consumption. It can operate with either an internal clock or an external clock. The output data rate from each part can vary from 4.17 to 470Hz.
