Gravity 16Bit 4-Channel ADC Analog Digital Converter I2C ADS1115

The DFRobot I2C ADS1115 16-bit ADC module can accurately capture and convert analog signals. The module is also compatible with the Raspberry Pi so you can easily connect and evaluate analog sensors to the Raspberry. This ADC module uses the 16-bit ADS1115 ADC chip and can be operated with a voltage of 3.3 to 5V. The chip has a precision reference voltage and a programmable gain adjustment (PGA), so accurate detection and conversion can be performed for both weak and highly variable signals. Therefore, it is also suitable for all kinds of applications where the main control board needs to accurately capture analog signals. An ADC module can capture analog signals from 4 channels. Due to the built-in I2C address selection switch, it supports cascading of two ADC modules. Therefore, you could evaluate analog signals from up to 8 channels.

Attention: The voltage at the analog input pins must be less than VCC+0.3V!
