Product Introduction
CS1232 is a high-precision, low-power Sigma-Delta ADC IC featuring one integrated Sigma-Delta ADC channel. The ADC employs a 3rd-order Sigma-Delta modulator with PGA amplification implemented via a low-noise instrumentation amplifier architecture, supporting selectable gains of 1, 2, 64, and 128. At PGA=128, the effective resolution reaches 20.8 bits. The CS1232 supports selectable output rates of 10Hz/80Hz. It integrates an on-chip RC oscillator, with the option to use an external crystal or directly input a clock signal via the CKIN/XTAL1 pin. The CS1232 also features ultra-low-power modes including Standby and Power Down.
Features
