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 automotive
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.
