Overview
The MAX1218ECQ+D, produced by Analog Devices Inc./Maxim Integrated, is a dual, monolithic, 12-bit analog-to-digital converter (ADC) designed for high-performance applications. This device operates at conversion rates of up to 170 million samples per second (Msps) and is optimized for dynamic performance up to a 250MHz input frequency. It is particularly suited for wideband applications due to its excellent signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR).
