ADS1234 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 plete 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)...
