The AD7329 is an 8-Channel, 12-Bit Plus Sign Successive Approximation ADC. The ADC has a high-speed serial interface that can operate at throughput rates up to TBD ksps.

The AD7329 can accept True Bipolar Analog input signals. The Ad7329 has four software selectable ranges, ±10V, ±5V, ±2.5V and 0 to 10V. Each analog input channel can be independently programmed to one of the input ranges by setting the appropriate bits in the Range Registers.

The Analog Input Channels AD7329 can be configured as single ended, fully differential or pseudo differential. Dedicated Control Register bits are used to configure the Analog inputs.

The ADC contains a 2.5V Internal reference. The AD7329 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. V_DD and V_SS supplies of ± 12V are required for this ± 12 V input range.
