AD7329 is a 1 MSPS, 8-channel, software-selectable, true bipolar input, 12-bit plus sign ADC
The AD7329 is an 8‑channel, 12‑bit plus‑sign successive‑approximation ADC featuring true bipolar input ranges and software‑selectable voltage ranges (+10 V, +5 V, +2.5 V, 0 V‑to‑+10 V). It offers a high‑speed serial interface and operates from a 2.5 V internal reference.
The device delivers up to 1 MSPS throughput, 20 MHz full‑power bandwidth, and low power dissipation (21 mW in normal mode). Detailed specifications, timing diagrams, and absolute maximum ratings are provided for design integration.
