1pc 16‑Bit I2C ADC Development Board Analog to Digital Converter Module Features: For micro-controllers without an analog-to-digital converter or when you want a higher-precision ADC, 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 e. 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 data-sheet table 5) so you can have up to 4 connected on a single 2-wire I2C bus for 16 single ended inputs. Four single-ended or two differential inputs. Programmable comparator; internal low-drift voltage reference; internal oscillator; internal PGA. This board/chip uses I2C 7-bit addresses between 0x48-0x4B, selectable with jumpers.
