The AD7323 is a 12-bit SAR ADC with four analog input channels, high input impedance, and low power consumption.
The AD7323 is a 4‑channel, 12‑bit plus‑sign successive‑approximation ADC that supports true bipolar input ranges and software‑selectable input ranges of +10 V, +5 V, +2.5 V, and 0‑10 V. It offers a high‑speed serial interface capable of up to 500 kSPS throughput and includes an internal 2.5 V reference, with optional external reference operation.
The device operates from a 12 V to 16.5 V supply, consumes only 17 mW at maximum speed, and provides a full‑power bandwidth of 22 MHz. It is supplied in a 16‑lead TSSOP package and is rated for an operating temperature range of –40 °C to +85 °C.
