Overview
The AD9432BSVZ-80, produced by Analog Devices Inc., is a 12-bit, monolithic sampling analog-to-digital converter (ADC) designed for high-speed conversion and ease of use. This ADC operates up to a 105 MSPS conversion rate and features outstanding dynamic performance across its full operating range. It requires a single 5.0 V power supply and a 105 MHz encode clock for full performance operation, eliminating the need for external reference or driver components in many applications. The digital outputs are TTL-/CMOS-compatible, and the device supports interfacing with 3.3 V logic through a separate output power supply pin.
