The AD7322 can handle True Bipolar Analog input signals. The Bipolar ranges are software selectable by programming the on board Range Register. Bipolar input ranges include 10V, 5V, 2.5V. The AD7322 can also handle a 0 to 10 V uniploar input range, which is also software selectable. Each analog input channel can be independently programmed to one of the input ranges by setting the appropriate bits in the Range Register. The Analog Input Channels can be configured as Single-Ended, Fully Differential or Pseudo Differential. Dedicated Control Register bits are used to configure the Analog inputs. The AD7322 contains a Channel Sequencer, allowing automatic conversions between each analog input channel. The ADC contains a 2.5V Internal reference. The AD7322 also allows for external Reference operation. If a 3V external reference is applied to the REFIN/OUT pin, the ADC can handle a True Bipolar 12 V Analog input range. Minimum VDD and VSS supplies of 12V are required for this 12 V input range.
