Overview
The AD9432BSQ-80 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, eliminating the need for external reference or driver components in many applications.
