ADS1115 16 Bit ADC 4 channel Module

Description:

• 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, it 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.

• The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115's connected on a single 2-wire I2C bus for 16 single ended inputs.
