Quad-Channel, 12-Bit, 50-MSPS ADC Reference Design With Low Noise, Low Distortion, DC and AC Inputs

This reference design demonstrates how to implement a single-ended-to-differential input path, which can be AC-coupled or DC-coupled for an ADC3422. It also explains how to design a high-input impedance, DC-coupled input path. The reference design can be used for applications such as low-power data (...)
