Custom ADS1115 16-bit ADC- 4-channel with programmable gain amplifier -STEMMA QT/For Qwiic

- Product Description -

◆ For microcontrollers without an analog-to-digital converter or when you need a higher precision ADC, the ADS1115 offers 16-bit accuracy at 860 samples per second via | 2C. The chip can be configured with 4 single-ended inputs
Incoming channel, or two differential channels. As a nice bonus, it even includes one or more programmable gain amplifiers up to x16 to help boost smaller single/differential signals to full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a wide range of signals, and is super easy to use. It is an excellent universal 16-bit converter.

The chip is quite small, so it comes with a splitter board with ferrite to keep AVDD and AGND quiet. The interface is done via 12C. The address can be changed to one of four options, so you can be on a single 2-wire 12C bus. Up to 4 ADS1115s are connected for 16 single-ended inputs.
◆ Comes with a little 0.1 "standard connector in case you want to use it with breadboards or perforated boards. Four mounting holes for easy installation. (Included does not include QT cable, need to search in the store)
◆ In order to get you started quickly, we have introduced a custom PCB in the shape of STEMMA QT, making it easy to connect. The STEMMA QT connectors on both sides are compatible with the SparkFun Qwiic 12C connector. This allows you to make a solderless connection between the development board and the ADS1115, or to link it with a variety of other sensors and accessories using compatible cables.
