• Manufacturer Part Number: MAX4357
• Description: The MAX4357 is a 32 x 16 highly integrated video crosspoint switch matrix with input and output buffers
• Manufacturer: Maxim

programmed in series times 112 bits per crosspoint
device. This programming method is most often used
at start-up to initially configure the switching matrix.
The MAX4357 guarantees operation with a single +5V
supply and a gain of +1V/V for standard video-input
signals (1V
switching system capable of gain = +2V/V while oper-
ating with a +5V single supply, combine the MAX4357
crosspoint switch with Maxim’s low-cost, high-perfor-
mance video amplifiers optimized for single +5V supply
operation (Figure 10). The MAX4450 single and

MAX4451 dual op amps are unity-gain-stable devices
that combine high-speed performance with rail-to-rail
outputs. The common-mode input voltage range
extends beyond the negative power-supply rail (ground
in single-supply applications). The MAX4450 is avail-
able in the ultra-small 5-pin SC70 package, while the
MAX4451 is available in a space-saving 8-pin SOT23
package. The MAX4383 is a quad op amp available in
a 14-pin TSSOP package. The MAX4380/MAX4381/
MAX4382 and MAX4384 offer individual high-imped-
ance output disable making these amplifiers suitable
for wired-OR connections.
