Overview
The MAX1219ECQ+TD, produced by Maxim Integrated (now part of Analog Devices Inc.), is a dual, monolithic, 12-bit analog-to-digital converter (ADC) designed for high-performance applications. This device is notable for its outstanding dynamic performance, making it ideal for wideband applications such as communications receivers, cable head-end receivers, and power-amplifier predistortion in cellular base-station transceivers. The MAX1219 operates from a single 1.8V power supply and supports AC-coupled, differential, or single-ended analog input operations.
