ADS1232 Datasheet 24-bit Analog-to-digital Converter

Manufacturer: Texas Instruments

Overview: www.ti.com ADS1232, ADS1234 SBAS350G – JUNE 2005 – AREDVSIS1E2D3J2A,NAUDARSY12203241 SBAS350G – JUNE 2005 – REVISED JANUARY 2021 ADS123x 2- and 4-Channel, 24-Bit, Delta-Sigma ADCs for Bridge Sensors.

General Description

The ADS1232 and ADS1234 (ADS123x) are precision, 24-bit, analog-to-digital converters (ADCs).

With a low-noise programmable gain amplifier (PGA), a precision delta-sigma ADC, and internal oscillator, the ADS123x provide a complete front-end solution for bridge sensor applications including weigh scales, strain gauges, and pressure sensors.

An input multiplexer (MUX) accepts either two (ADS1232) or four (ADS1234) differential inputs.

Key Features

  • Complete front-end for bridge sensors.
  • 23.5-bits effective resolution at gain = 1.
  • 19.2-bits noise-free resolution at gain = 64.
  • Low-noise PGA.
  • Selectable gains of 1, 2, 64, and 128.
  • RMS noise:.
  • 17 nV at 10 SPS at gain = 128.
  • 44 nV at 80 SPS at gain = 128.
  • 100-dB simultaneous 50-Hz and 60-Hz rejection.
  • Flexible clocking:.
  • Low-drift internal oscillator.
  • Optional external crystal.
