Description

The AD7324 is a 4-Channel, 12-Bit plus Sign Successive Approximation ADC. The ADC has a high speed serial interface that can operate at throughput rates up to 1 Msps.

The AD7324 can accept true bipolar Analog Input signals. The AD7324 has four software selectable inputs Ranges, ±10V, ±5V, ±2.5V and 0 to 10V. Each analog input channel can be independently programmed to one of the four input ranges.

The Analog input channels on the AD7324 can be programmed to be Single-Ended, true Differential or Pseudo Differential.

The AD7324 contains a 2.5V Internal reference. The AD7324 also allows for external Reference operation. If a 3V reference is applied the REF IN/OUT pin the AD7324 can accept a true Bipolar ±12V Analog Input. Minimum VDD and VSS supplies of ±12V are required for the ±12V Input Range.
