The ADS1115 and ADS1015 4-channel  breakout boards are perfect for adding high-resolution analog to digital conversion to any microprocessor-based project.  These boards can run with power and logic signals between 2v to 5v, so they are compatible with all common 3.3v and 5v processors.  As many of 4 of these boards can be controlled from the same 2-wire I2C bus, giving you up to 16 single-ended or 8 differential channels.  A programmable gain amplifier provides up to x16 gain for small signals.

These two boards are very similar, differing only in resolution and speed.  The ADS1115 has higher resolution and the ADS1015 has a higher sample rate.

ADS1115 Features:

  • Resolution: 16 Bits
  • Programmable Sample Rate: 8 to 860 Samples/Second
  • Power Supply/Logic Levels: 2.0V to 5.5V
  • Low Current Consumption: Continuous Mode: Only 150µA Single-Shot Mode: Auto Shut-Down
  • Internal Low-Drift Voltage Reference
  • Internal Oscillator
  • Internal PGA: up to x16
  • I2C Interface: 4-Pin-Selectable Addresses
  • Four Single-Ended or 2 Differential Inputs
  • Programmable Comparator
