This document is the AD9432 datasheet. The AD9432 is a 12-bit, 80 MSPS/105 MSPS ADC with an on-chip reference and track-and-hold circuit, which enables high accuracy and high speed conversion.
The AD9432 is a 12‑bit, monolithic sampling analog‑to‑digital converter optimized for high‑speed conversion and ease of use. It operates up to 105 MSPS with a typical power dissipation of 850 mW and requires a single 5.0 V supply. The device features on‑chip reference, track‑and‑hold, and TTL/CMOS‑compatible digital outputs.
The datasheet provides detailed specifications, pin configurations, timing diagrams, thermal characteristics, and application notes, including guidance for driving the ADC with the AD8138 differential output op‑amp. Ordering information for LQFP and TQFP packages is also included.
