Description:
Simply connect GND to ground, VDD to the logic power supply and SCL/SDA to the I2C port of the microcontroller and run the sample code to start reading the data.
For microcontrollers without analog-to-digital converter or when you want a higher precision ADC, the ADS1115 offers 16-bit accuracy at 3300 samples/second compared to I2C.
The chip can be configured as 4 single-ended input channels, or two differential channels.
It even includes a programmable gain amplifier, up to x16, to increase smaller single/differential signals across the entire range.
The chip is quite small, so it comes on a ferrite release board to keep the AVDD and AGND quiet. Interface is via I2C.
