Overview
The AD9432BSVZ-105 is a 12-bit, monolithic sampling analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is optimized for high-speed conversion and ease of use, making it suitable for a variety of high-performance applications. The AD9432 operates up to a 105 MSPS conversion rate and features outstanding dynamic performance over its full operating range. It requires only a single 5.0 V power supply and a 105 MHz encode clock for full performance operation, with no external reference or driver components needed for many applications. The digital outputs are TTL-/CMOS-compatible, and a separate output power supply pin supports interfacing with 3.3 V logic.
