Overview
The AD9253BCPZ-125 is a quad, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for low cost, low power, small size, and ease of use, making it ideal for applications where high dynamic performance and compact packaging are critical. The AD9253 operates at conversion rates of up to 125 MSPS and requires a single 1.8 V power supply. It is compatible with LVPECL-, CMOS-, and LVDS-compatible sample rate clocks, eliminating the need for external reference or driver components in many applications.
