Overview
The MAX19542EGK+TD is a 12-bit, 170Msps analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This monolithic ADC is optimized for outstanding dynamic performance at high-IF frequencies of 300MHz and beyond. It is designed to operate with conversion rates up to 170Msps while consuming only 907mW, making it ideal for wideband applications such as power-amplifier predistortion in cellular base-station transceiver systems, cable head-end receivers, and various communication and test equipment.
