Overview
The AD9656BCPZ-125 is a quad, 16-bit, 125 MSPS analog-to-digital converter (ADC) designed by Analog Devices Inc. This device is optimized for low cost, low power, small size, and ease of use, making it ideal for applications where dynamic performance and compact packaging are critical. The ADC operates at a conversion rate of up to 125 MSPS and features an on-chip sample and hold circuit. It requires a single 1.8 V power supply and supports LVPECL-, CMOS-, and LVDS-compatible sample rate clocks.
