The AD7321 can accept true bipolar analog input signals. The AD7321 has four software-selectable input ranges, ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V. Each analog input channel is independently programmed to one of the four input ranges. The analog input channels on the AD7321 are programmed to be single-ended, true differential, or pseudo differential.
The ADC contains a 2.5 V internal reference. The AD7321 also allows for external reference operation. If a 3 V reference is applied to the REFIN/OUT pin, the AD7321 can accept a true bipolar ±12 V analog input. A minimum of ±12 V VDD and VSS supplies are required for the ±12 V input range. The ADC has a high speed serial interface that can operate at throughput rates up to 500 kSPS.
Product Highlights
- The AD7321 can accept true bipolar analog input signals, ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V unipolar signals.
- The two analog inputs are configured as two single-ended inputs, one true differential input pair, or one pseudo differential input.
- A 500 kSPS serial interface. SPI®-/QSPI™-/DSP-/ MICROWIRE™-compatible interface.
- Low power, 18 mW, at a maximum throughput rate of 500 kSPS.
- Channel sequencer.
