ADS1232 - Burr-Brown

ADS1232 24-Bit Analog-to-Digital Converter

The ADS1232 and ADS1234 are precision analog-to-digital (A/D) converters featuring true 23.5 effective-bit performance and exceptional ease of use. Selectable gains of 1, 2, 64, or 128 allow full-scale differential input ranges of ±2.5V to ±19.5mV with a +5V reference. While the ADS1232 offers a two-channel differential input and a built-in temperature senso.
