Description

The MAX4027 is a triple, wideband, 2-channel, noninverting gain-of-two video amplifier with input multiplexing, capable of driving up to two back-terminated video loads. The MAX4027 features current-mode feedback amplifiers configured for a gain of two (+6dB) with a -3dB large-signal bandwidth of 200MHz. The device has low (0.012%/0.014°) differential gain and phase errors, and operates from ±5V supplies.

The MAX4027 is ideal for use in broadcast and graphics video systems because of the low 2pF input capacitance, channel-to-channel switching time of only 15ns, and wide 62MHz, large-signal 0.1dB bandwidth. High-impedance output disabling allows the MAX4027 to be incorporated into large switching arrays with minimal interaction with the source. Specified over the -40°C to +85°C extended temperature range, the MAX4027 is available in 14-pin SO and TSSOP packages.
