Hat ADC v1.1
SKU:U069-V11
Description
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 self-calibration and adjustable gain. The chip has an internal 2.048V reference and a differential full-scale range of ±2.048V/PGA. 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.
The module terminals provide a ground-referenced single-ended input, with the negative terminal connected to GND. The nominal 0 ~ 12V measurement range applies at PGA = 1; higher gains reduce the measurement range.
