Chinese: Σ-Δ (Sigma-Delta) 24-bit high-precision ADC (analog-to-digital converter) is a common ADC design that utilizes sigma-delta modulation to achieve high-precision conversion of analog signals to digital signals. Σ-Δ ADCs are suitable for many application scenarios that require high accuracy and low distortion, such as audio processing, sensor measurements, and precision instruments. Its operating principle and characteristics make it an integral part of many high-performance systems.
