Overview
The AD9253TCPZR7-125EP is a quad, 14-bit, 125 MSPS analog-to-digital converter (ADC) designed by Analog Devices Inc. This ADC is optimized 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 with a single 1.8 V power supply and supports LVPECL-, CMOS-, and LVDS-compatible sample rate clocks. The device features an on-chip sample-and-hold circuit and does not require external reference or driver components for many applications.
