ADS1232IPW 24 Bit 2-Ch Analog to Digital Converter IC - TSSOP-24
The ADS1232 is 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. The ADS1232 also includes a temperature sensor to monitor ambient temperature. The low-noise PGA has a selectable gain of 1, 2, 64, or 128, supporting a full-scale differential input of ±2.5 V, ±1.25 V, ±39 mV, or ±19.5 mV.
The delta-sigma ADC provides a maximum of 23.5-bits effective resolution, and supports two data rates: 10 SPS (providing 50-Hz and 60-Hz rejection) and 80 SPS. The ADS123x can be clocked externally using an oscillator or a crystal, or by the internal oscillator.
Offset calibration is performed on-demand, and the ADS123x can be put in a low-power standby mode or shut off completely in power-down mode. The ADS123x are operated through simple pin-driven control—there are no digital registers to program.
