ADS1114 16-Bit 2-Channel Precision Analog to Digital Converter

  • Configure 2-Channel Single-Ended Inputs
  • Configure 1-Channel Differential Input
  • 16-Bit Resolution
  • Programmable Gain Amplifier
  • ±.256VDC to ±4.096VDC Input Voltage Range
  • Combine 2 Devices per I2C Port


The ADS1114 is a precision dual-channel 16-bit analog to digital converter (ADC), capable of reading analog voltages at 860 samples per second.

It is ideal for monitoring

  • batteries,
  • precision thermocouples, or
  • high resolution sensors.

Up to two ADS1114 converters can share a single I2C port, making it ideal solution for applications that may require future expansion.

The ADS1114 has two single-ended inputs or one differential input depending on software configuration. It is also equipped with a programmable gain amplifier (PGA) for reading ±.256VDC, ±.512VDC, ±1.024VDC, ±2.048VDC, and ±4.096VDC.


This is a general purpose I²C device compatible with all computing platforms and IoT technologies, including Raspberry Pi, BeagleBone, Arduino, Particle, BridgeX5, and many more.  All devices support a strict +5V I²C Bus standard.

Mini Modules

Our mini modules provide a standardized footprint to simplify the design of your project, and allow for a smaller form factor without sacrificing the plug-and-play  ease of use that our product line affords.

All I²C Mini Modules are designed to operate at 5VDC. Using a convenient quick connect 4-Pin plug, devices can be daisy-chained onto the I²C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application.

Pull-up resistors are included with all master devices. If you are wiring in your own I²C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.

All mini modules are 50.8 x 31.75 mm.
