Description

Description:
For microcontrollers without analog-to-digital converters or if you want an ADC with higher accuracy, the ADS115 provides 16-bit accuracy with 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels or two differential channels. As a nice bonus, it even includes a programmable gain amplifier (up to x16) that helps amplify smaller single/differential signals across the entire range. The chip is quite small, so it comes on a breakout board with ferrites to keep AVDD and AGND quiet. The interface is via I2C. Simply connect GND to ground, VDD to your logic power supply and SCL/SDA to the I2C port of your microcontroller, and run the sample code to start reading data.
