Adafruit 1085 ADC 16-bit Analogue to Digital Converter 4 Channel (ADS1115)

The Adafruit ADS1115 16-bit ADC is a tiny breakout board which provides 4 x ADC channels over 2-wire I2C. The chip can be configured as either 4 x single ended channels or as 2 x differential channels with at up to 860 samples per second. Small signals can be amplified up to 16 times by the built-in programmable gain amplifier. The board also features noise cancelling to keep the supply lines clean. It uses one of four possible I2C addresses allowing you to run 4 x boards on the same 2-wire bus. Sample code is available for Raspberry Pi or Arduino.

We also supply a 12-bit version 75-0562 which has a higher data rate.
