{"title":"M5StickC ADC HAT ADS1100","handle":"m5stickc-adc-hat-ads1100","url":"/products/m5stickc-adc-hat-ads1100","description":"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 ADS1100, which is a fully differential, 16-bit, self-calibrating, delta-sigma A/D converter. Extremely easy to design with and configure, the ADS1100 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. ADS1100 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.   Product Features  M5StickC Compatible Input: 0-12V Software Development Platform: Arduino, UIFlow(Blockly, Python) ADS1100  16-bits Resolution CONTINUOUS SELF-CALIBRATION SINGLE-CYCLE CONVERSION PROGRAMMABLE GAIN AMPLIFIER GAIN = 1, 2, 4, OR 8 LOW NOISE: 4μVp-p PROGRAMMABLE DATA RATE: 8SPS to 128SPS INTERNAL SYSTEM CLOCK I2C INTERFACE: address 0x48    Include  1x ADC HAT 1x 2 Pin 3.96 Pitch Terminal  Application  Analog Signal Capture  Learn Links   Datasheet - ADS1100   Code  1.
