Description

The MAX4028/MAX4029 are 5V, triple/quad, 2:1 voltage-feedback 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 fixed-gain video output buffers make the MAX4028/MAX4029 ideal for video-source switching applications such as entertainment systems, video projectors, and displays/ TVs. Both devices have 20ns channel switching times and low ±10mVP-P switching transients, making them ideal for high-speed video switching applications such as on-screen display (OSD) insertion.

The MAX4028/MAX4029 have a -3dB large-signal (2VP-P) bandwidth of 130MHz, a -3dB small-signal bandwidth of 210MHz, and a 300V/µs slew rate. Low differential gain and phase errors of 0.2% and 0.4°, respectively, make these devices ideal for broadcast video applications.

The MAX4028/MAX4029 are specified over the -40°C to +85°C extended temperature range and are offered in 16-pin and 20-pin TSSOP/SO packages.
