Overview
The MAX1198ECM+D, produced by Analog Devices Inc./Maxim Integrated, is a 3.3V, dual, 8-bit analog-to-digital converter (ADC) designed for high-performance and low-power applications. This ADC features fully differential wideband track-and-hold (T/H) inputs, driving two ADCs, and is optimized for low power consumption, small size, and high dynamic performance. It is particularly suited for applications in imaging, instrumentation, and digital communications.
