Description
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.

- Low power: 335 μW/channel.
- Input-referred noise: 8 μVPP
(150-Hz BW, G = 6).
- Input bias current: 200 pA.
- Data rate: 125 SPS to 8 kSPS.
- CMRR: 120 dB.
- Programmable gain: 1, 2, 3, 4, 6, 8, or 12.
- Supplies: unipolar or bipolar.
- Analog: 2.7 V to 5.25 V.
- Digital: 1.7 V to 3.6 V.
- Built-in right leg drive amplifier, lead-off detection.
