The 4 channel ADS1115 16 BIT ADC I²C module is a great general purpose 16-bit converter. The chip can be configured as 4 single-ended input channels, or two differential channels.

It contains 4 precision, low-power, 16-bit, I2C-compatible, analog-to-digital converters (ADCs). It also has a low-drift voltage reference and an oscillator as well as a programmable gain amplifier (PGA) to help boost smaller single/differential signals to the full range and a digital comparator.

Features

• low-drift reference voltage
