Overview
The MAX105ECS+T, produced by Analog Devices Inc./Maxim Integrated, is a dual, 6-bit, analog-to-digital converter (ADC) designed for high-speed and precise digitization of in-phase (I) and quadrature (Q) baseband signals. This device is particularly suited for applications requiring fast and accurate conversion of analog signals to digital data. The MAX105 operates from a +5V analog supply and features LVDS output ports operating at +3.3V, with a typical power dissipation of 2.6W. It is packaged in an 80-pin TQFP package with an exposed paddle and is specified for the extended temperature range of -40°C to +85°C.
