Features:

  • 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.
  • 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.
