The ADS8327/28 is a high-speed, low power, successive approximation register (SAR) analog-to-digital
converter (ADC) that uses an external reference. The architecture is based on charge redistribution, which
inherently includes a sample/hold function.
The ADS8327/28 has an internal clock that is used to run the conversion but can also be programmed to run the
conversion based on the external serial clock, SCLK.
The ADS8327 has one analog input. The analog input is provided to two input pins: +IN and -IN. When a
conversion is initiated, the differential input on these pins is sampled on the internal capacitor array. While a
conversion is in progress, both +IN and -IN inputs are disconnected from any internal function.
The ADS8328 has two inputs. Both inputs share the same common pin - COM. The negative input is the same
as the -IN pin for the ADS8327. The ADS8328 can be programmed to select a channel manually or can be
programmed into the auto channel select mode to sweep between channel 0 and 1 automatically.
