Introduction

AI Translation

The ADS1232 and ADS1234 (ADS123x) are precision 24-bit analog-to-digital converters (ADCs). With a low-noise programmable gain amplifier (PGA), a precision Δ-Σ ADC, and an internal oscillator, the ADS123x provides a complete front-end solution for bridge sensor applications, including weighing scales, strain gauges, and pressure sensors. The input multiplexer (MUX) accepts dual (ADS1232) or quad (ADS1234) differential inputs. The ADS1232 also includes a temperature sensor for monitoring the ambient temperature. The low-noise PGA has selectable gains of 1, 2, 64, or 128, supporting full-scale differential inputs of ±2.5V, ±1.25V, ±39mV, or ±19.5mV. The Δ-Σ ADC can provide up to 23.5 bits of effective resolution and supports two data rates: 10SPS (providing 50Hz and 60Hz rejection) and 80SPS. The ADS123x can be externally timed using an oscillator or a crystal, or it can be timed by the internal oscillator. Offset voltage calibration can be performed on demand, and the ADS123x can be placed in a low-power standby mode or completely shut down in a power-down mode. The ADS123x can be operated through simple pin-drive control without programming digital registers. Data is output through a two-wire serial interface directly connected to an MSP430 or other microcontrollers.
