General 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 sig-
nal, 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 selec-
table. Selectable clamp/key-clamp inputs and fixed-gain
video output buffers make the MAX4028/MAX4029 ideal
for video-source switching applications such as automo-
tive entertainment systems, video projectors, and dis-
plays/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/s 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.
