Description For microcontrollers without an analog to digital converter or when you want a higher precision ADC the ADS1015 provides 12 bit precision at 3300 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 12 bit converter The chips fairly small so it comes on a 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 ADS1015s connected on a single 2 wire I2C bus for 16 single ended inputs Package included 3 x Analog to Digital Converter
