Overview
The MAX1184ECM+D, produced by Analog Devices Inc./Maxim Integrated, is a 3V, dual 10-bit analog-to-digital converter (ADC) designed for high-performance applications. This ADC features fully-differential wideband track-and-hold (T/H) inputs driving two pipelined, nine-stage ADCs. It is optimized for low-power, high dynamic performance, making it suitable for various demanding applications such as imaging, instrumentation, and digital communication. The device operates from a single 2.7V to 3.6V supply and consumes low power, with a typical signal-to-noise ratio (SNR) of 59.5dB at an input frequency of 20MHz and a sampling rate of 20Msps.
