Analog Devices AD7321 Datasheet
The AD7321 is a 2‑channel, 12‑bit plus sign successive‑approximation ADC built on Analog Devices' iCMOS process. It accepts true bipolar analog inputs and offers four software‑selectable input ranges (+10 V, +5 V, +2.5 V, and 0‑10 V unipolar). The device features a high‑speed serial interface capable of up to 500 kSPS throughput and operates with low power consumption (18 mW in normal mode).
The ADC is supplied in a 14‑lead TSSOP package and includes an internal 2.5 V reference (or can use an external reference). Detailed specifications cover dynamic performance, conversion timing, absolute maximum ratings, and recommended layout and grounding practices for optimal operation.
