For micro controllers without an analog-to-digital converter such as Raspberry Pi or want extra ADC pin such as in case of ESP8266 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.
To get you started, we have example code for both the Raspberry Pi (Pi Python library) and Arduino (ADS1X15 Arduino library) Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller’s I2C port and run the example code to start reading data.
- WIDE SUPPLY RANGE: 2.0V to 5.5V

- INTERNAL OSCILLATOR
- INTERNAL PGA
- I2C INTERFACE: Pin-Selectable Addresses
- FOUR SINGLE-ENDED OR TWO DIFFERENTIAL INPUTS
- PROGRAMMABLE COMPARATOR
- This board/chip uses I2C 7-bit addresses between 0x48-0x4B, selectable with jumpers
The device is not operating although I have connected the wired as mentioned in the manual.
damaged / faulty unit received. It is the first purchase but got disappointed. Even the return procedure is a hassle / time taking. Th new unit should be sent as soon the fault reported but instead a lengthy process was communicated to sent the unit back first and then replacement will be provided.
I really love your product as i experience before, on the other hand your customer relationship is also good but your service regarding TCS is very bad. because as i ordered this item 4-5 day before but i still not received.
Did not work. The bulb is recognised but registration does not complete after finding ID. Tested on 3 different routers including zong device. I even changed dns. disappointed
