Overview
The MAX1124EGK+D, produced by Analog Devices Inc./Maxim Integrated, is a high-performance, monolithic 10-bit analog-to-digital converter (ADC) designed for outstanding dynamic performance at high intermediate frequencies (IF) up to 500MHz. This ADC operates at conversion rates of up to 250 million samples per second (Msps) while consuming only 477mW of power. It is optimized for wideband applications, including digital predistortion in cellular base-station transceiver systems, radar and satellite subsystems, and various broadband communication systems.
