Main application scenarios: Data acquisition and bridge sensors.
CS1239 is a 24-bit high-precision ADC that integrates a high-precision ADC signal chain, a low-drift LDO, a low-temperature drift reference voltage, a high-precision oscillator, and a 3-wire communication interface. Specifically, the ADC signal chain includes: Input MUXP/MUXN, a level shift module (LVSHIFT), a low-noise programmable gain amplifier (PGA), a 24-bit Sigma-Delta ADC, and a digital filter. It supports bridge sensors and is suitable for industrial measurement.
