Overview
The MAX1213EGK+D is a high-performance, 12-bit analog-to-digital converter (ADC) designed by Maxim Integrated, now part of Analog Devices Inc. This monolithic ADC is optimized for outstanding dynamic performance at high-IF frequencies, making it suitable for a variety of broadband applications. It operates with conversion rates up to 170 Msps and consumes only 788 mW of power at a sampling frequency of 170 MHz and an input frequency of 65 MHz. The device features a single 1.8V supply and supports both differential and single-ended analog input configurations, which can be AC- or DC-coupled.
