Overview
The MAX1198ECM+TD is a 3.3V, dual, 8-bit analog-to-digital converter (ADC) designed by Analog Devices Inc./Maxim Integrated. This ADC is optimized for low power consumption, small size, and high dynamic performance, making it suitable for various applications such as imaging, instrumentation, and digital communications. It operates from a single 2.7V to 3.6V supply and features fully differential wideband track-and-hold (T/H) inputs, driving two ADCs. The device delivers excellent dynamic performance with a typical signal-to-noise and distortion (SINAD) of 48.1dB at an input frequency of 50MHz and a sampling rate of 100Msps.
