Hat ADC

SKU:U069

Description

Hat ADC is a high-precision analog-to-digital conversion module designed specifically for the StickC series. It integrates the ADS1100 16-bit Δ-Σ ADC chip, featuring self-calibration and programmable gain. The chip uses its 3.3V supply as the reference, with a differential full-scale range of ±3.3V/PGA. Through optimized peripheral circuit design, the module extends this capability to a DC voltage measurement range of 0 ~ 12V. Using a standard I2C communication interface, the module enables accurate and stable voltage acquisition, making it suitable for industrial sensor signal processing, battery voltage monitoring, and various analog signal acquisition applications.

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.
