Overview
The AD9650BCPZ-25 is a dual, 16-bit analog-to-digital converter (ADC) designed by Analog Devices Inc. This device is optimized for digitizing high-frequency, wide dynamic range signals with input frequencies up to 300 MHz. The AD9650 features a multistage, differential pipelined architecture with integrated output error correction logic, ensuring high performance and accuracy. It operates from a single 1.8 V analog supply and a separate 1.8 V digital output driver supply, supporting both CMOS and LVDS output modes. The device is available in a 64-lead LFCSP package and is specified over the industrial temperature range of −40°C to +85°C.
