The AD7323 is a 12-bit plus sign SAR ADC with true bipolar input ranges and software-selectable input ranges. It features four analog input channels, a channel sequencer, and single-ended, true differential, and pseudo differential analog input capability. Its characteristics include high-speed serial interface, low power consumption, internal 2.5V reference voltage, etc.
The AD7323 is a 4‑channel, 12‑bit plus‑sign successive‑approximation ADC designed on iCMOS technology. It offers true bipolar input ranges that can be software‑selected (+10 V, +5 V, +2.5 V, and 0 V to +10 V) and supports single‑ended, true differential, or pseudo‑differential configurations. The device includes an internal 2.5 V reference, a high‑speed serial interface, and low power consumption (17 mW).
Key specifications include a maximum throughput rate of 500 kSPS, a full‑power bandwidth of 22 MHz, and operation over a –40 °C to +85 °C temperature range. The ADC is supplied in a 16‑lead TSSOP package and is available in several ordering options for temperature and packaging.
