AD7195 Low Noise 24-Bit Sigma-Delta ADC Datasheet
The AD7195 is a low noise, 24-bit Sigma-Delta analog-to-digital converter (ADC) designed for high-precision measurement applications. It features an integrated low noise gain stage that allows small signals to be applied directly to the input. The device includes built-in AC excitation to eliminate induced DC offset voltages in bridge sensors. It supports two digital filter options, multiple input channel configurations, and programmable gain, making it suitable for applications such as electronic scales, pressure measurement, temperature measurement, chromatography, and medical instruments. This manual is written in Chinese.
