ADS1292 Overview
The ADS1291, ADS1292, and ADS1292R are multichannel, simultaneous sampling, 24-bit, deltasigma (ΔΣ) analog-to-digital converters (ADCs) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator. The ADS1291, ADS1292, and ADS1292R incorporate all.
