ADS1115 4-Channel ADC Converter
DESCRIPTION
The ADS1115 offers analog to digital conversion with 16-bit accuracy and up to 860 samples per second, ideal if your microcontroller does not have analog-to-digital conversion or if you need a very accurate conversion.
The chip can be configured to be usable with 4 separate inputs or 2 differential inputs, it also has a level amplifier (up to x16), which is very convenient if you have to process weak signals. The module can work with logic and power supply ranging from 2 to 5.5VDC, which makes it very convenient to use regardless of the situation.
The module has ferrites to reduce input noise. The interface is done in I2C with 4 available addresses, so it is possible to chain 4 modules on the same I2C, i.e. 16 possible inputs.
