Overview
The AD9645BCPZRL7-125, produced by Analog Devices Inc., is a dual, 14-bit, 125 MSPS analog-to-digital converter (ADC) designed for low cost, low power, small size, and ease of use. This ADC features an on-chip sample-and-hold circuit and is optimized for outstanding dynamic performance and low power consumption. It operates at a conversion rate of up to 125 MSPS and is suitable for applications where a small package size is critical. The device requires a single 1.8 V power supply and supports LVPECL-, CMOS-, and LVDS-compatible sample rate clocks. No external reference or driver components are required for many applications, making it a versatile and efficient solution.
