Overview
The MAX1123EGK+TD is a high-performance, monolithic 10-bit analog-to-digital converter (ADC) designed by Analog Devices Inc./Maxim Integrated. This ADC is optimized for outstanding dynamic performance at high intermediate frequencies (IF) up to 500MHz, making it ideal for wideband applications such as digital predistortion in cellular base-station transceiver systems. The MAX1123 operates at conversion rates of up to 210Msps while consuming only 460mW from a single 1.8V supply. Its excellent signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR) ensure high-quality signal processing across a wide frequency range.
