MAX4028/MAX4029 EVALUATION KIT AVAILABLE Triple/Quad, 2:1 Video Multiplexer-Amplifiers with Input Clamps General Description The MAX4028/MAX4029 are 5V, triple/quad, 2:1 voltagefeedback multiplexer-amplifiers with input clamps and a fixed gain of +2V/V (6dB). Channel 1 (IN1A and IN1B) inputs are clamped to the video sync tip of the input signal, while the remaining inputs can be clamped to either the video sync tip or the video sync of channel 1 (IN1_). The latter is referred to as a key clamp and is pin selectable. Selectable clamp/key-clamp inputs and fixedgain video output buffers make the MAX4028/MAX4029 ideal for video-source switching applications such as entertainment systems, video projectors, and displays/ TVs.
