Overview
The AD9253BCPZ-125 is a quad, 14-bit analog-to-digital converter (ADC) designed by Analog Devices. It operates at conversion rates of up to 125 million samples per second (MSPS) and is optimized for low cost, low power, small size, and ease of use. The ADC features an on-chip sample-and-hold circuit 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.
