Overview
The AD9695BCPZ-625 is a dual, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for high-performance applications requiring direct sampling of wide bandwidth analog signals up to 2 GHz. It features an on-chip buffer and a sample-and-hold circuit, optimized for low power, small size, and ease of use. The AD9695 is particularly suited for communications applications due to its high sampling rates of 1300 MSPS and 625 MSPS, excellent linearity, and low power consumption in a compact 64-lead Lead Frame Chip Scale Package (LFCSP).
