M5StickC ADC HAT ADS1110 v1.1

The M5Stack M5StickC ADC HAT V1.1 is another type of C-HAT specifically designed for the M5StickC controller. Same as the ADC unit, this is an ADC converter for M5StickC. Packed with an ADC converter chip ADS1110, which is a fully differential, 16-bit, self-calibrating, delta-sigma A/D converter. Extremely easy to design with and configure, the ADS1110 allows you to obtain precise measurements with a minimum of effort. The ADS1100 consists of a delta-sigma A/D converter core with adjustable gain, a clock generator, and an I2C interface. The ADS1110 itself is able to accept a differential input from -5 ~ +5 V, but we have limited the input to 0 to 12V by adding the peripheral circuit design of this IC. Features

* Programmable gain amplifier (PGA = 1, 2, 4 or 8 continuous self-calibration)

* Low noise (10uVP-P)

* I2C Communication

* Built-in reference (accuracy: 2.048V ± 0.05%)
