ADS1115 16-BIT ADC - 4 CHANNEL WITH PROGRAMMABLE GAIN AMPLIFIER
ADS1115 16-BIT ADC - 4 CHANNEL WITH PROGRAMMABLE GAIN AMPLIFIER
For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115
provides 16-bit precision at 860 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, to help boost
up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic,
can measure a large range of signals and its super easy to use. It is a great general purpose 16 bit converter.
The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is
done via I2C.
Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run
the example code to start reading data.
