ADC HAT

SKU:U069-V11

Description

ADC HAT is another type of C-HAT specifically design for M5StickC controller. Same as ADC unit, this is an ADC converter component for stickc. 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.
ADS1110 itself is able to accept a differential input from -5 ~ +5 V, but we have limited the input to 0~12V by adding on the peripheral circuit design of this IC.

The main differences from the previous version of HAT-ADC are as follows:1. Input channels: The ADS1110 has single-ended and differential input channels, while the ADS1100 has only single-ended input channels.2. Reference voltage: The ADS1100 only has a fixed 1.25V internal reference voltage, while the ADS1110 has two options, internal reference voltage and external reference voltage, which can be programmed according to needs.3. Resolution: ADS1110 has 16-bit resolution, while ADS1100 only has 12-bit resolution.4. Sample rate: The maximum sampling rate of the ADS1110 is 860 samples/sec, while the maximum sampling rate of the ADS1100 is 128 samples/sec.
