ADS1292R - 24-Bit Analog Front-End

This page provides the datasheet information for the ADS1292R, a member of the ADS1291 24-Bit Analog Front-End family.

Datasheet Summary

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.

Features

  • 1 Two low-noise PGAs and two high-resolution ADCs (ADS1292 and ADS1292R).
  • 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.
