Welcome to our shop! The ADC is a precision analog-to-digital converter (ADC). It is a chip that can provide 16-bit sampling precision, packaged in an ultra-small MSOP-10 package. The power supply is 3.3V, with programmable data speed rate from 8sps to 860sps. It has an internal PGA that supports 16-bit sampling precision. The I2C port allows for pin-selectable addresses and channels quantity. It has 4 single-ended or 2 differential inputs, with a programmable comparator range of 2/3~16. This ADC also has internal NPT support for data transmission through an I2C compatible series port. It has 4 channel I2C addresses that can be chosen and only requires a 3.3V working power supply. Its main function is to detect analog signals and convert them to digital signals. You can use this converter to connect analog sensors such as joysticks, NTC, temperature, and dust sensors to your Raspberry Pi and read the collected signals.
