The ADS1232 and ADS1234 are precision analog-to-digital converters with true 23.5-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. The ADS1232 offers a two-channel differential input and a built-in temperature sensor, while the ADS1234 features a four-channel differential input multiplexer. An on-board low-noise gain amplifier with low differential input current minimizes errors when using high-impedance transducers. The devices also feature a low current driver to accommodate different applications.
