The AD7324 is a 4-channel, 12-bit plus sign ADC with true bipolar input ranges and software-selectable input ranges. It features high-speed serial interface, low power consumption, and high precision.
The AD7324 from Analog Devices is a 4‑channel, 12‑bit plus sign successive‑approximation ADC built on iCMOS technology. It supports true bipolar input signals and offers four software‑selectable input ranges: +10 V, +5 V, +2.5 V, and 0 V to +10 V. The device provides a high‑speed serial interface capable of up to 1 MSPS conversion rate.
Key features include low power consumption (31 mW at 1 MSPS), a 2.5 V internal reference, multiple input configurations (single‑ended, true differential, pseudo‑differential), and a 16‑lead TSSOP package. Detailed specifications, timing diagrams, and application notes are provided throughout the handbook.
