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 it's super easy to use.
