Overview
The MAX1217ECQ+D is a dual, monolithic, 12-bit analog-to-digital converter (ADC) designed by Analog Devices Inc./Maxim Integrated. This high-speed ADC is optimized for broadband applications, offering outstanding dynamic performance up to a 250MHz input frequency. It operates at conversion rates of up to 125Msps, consuming only 650mW per channel. The device is particularly suited for wideband applications such as communications receivers, cable head-end receivers, and power-amplifier predistortion in cellular base-station transceivers.
