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 1 MSPS. The ADC has a high-speed serial interface that can operate at throughput rates up to 250 kSPS.
The AD7329 can accept True Bipolar Analog input signals. The Ad7329 has four software selectable ranges, ±10 V, ±5 V, ±2.5 V and 0 to 10 V. 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 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 2.5 V Internal reference. The AD7329 also allows for external Reference operation. If a 3 V external reference is applied to the REFIN/OUT pin, the ADC can handle a True Bipolar ± 12 V Analog input range. VDD and VSS supplies of ± 12 V are required for this ± 12 V input range.
The AD7329 has multiplexer output pins and ADC input pins. These allow the user to insert buffers, differential amplifiers or antialiasing filters, if required, between the Multiplexer and the ADC. This means that for eight analog inputs only a single driver is required for the AD7329.
The AD7329 has a number of power down mode to reduce power consumption at lower throughput rates.
