Overview
The AD9253TCPZ-125EP is a quad, 14-bit, 125 MSPS 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 ADC operates with a single 1.8 V power supply and supports LVPECL-, CMOS-, and LVDS-compatible sample rate clocks. It features an on-chip sample-and-hold circuit and does not require external reference or driver components for many applications.
