Overview
The AD9253BCPZRL7-125 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. It operates at conversion rates of up to 125 MSPS and requires a single 1.8 V power supply. The ADC features an on-chip sample-and-hold circuit and supports LVPECL-, CMOS-, and LVDS-compatible sample rate clocks without the need for external reference or driver components in many applications.
