Hat ADC v1.1 is a high-precision analog-to-digital conversion module specifically designed for the StickC series. It integrates the ADS1110 16-bit Δ-Σ ADC chip, featuring fully differential inputs, self-calibration, and adjustable gain. The chip itself supports a differential input range of -5V ~ +5V. Through optimized peripheral circuit design, the module extends this capability to a DC voltage measurement range of 0 ~ 12V. It also includes a built-in 2.048V reference voltage, enabling stable and accurate signal acquisition without the need for an external reference source. The module communicates via a standard I2C interface and is suitable for applications such as industrial sensor signal processing, battery voltage monitoring, and various analog signal acquisition scenarios.
