19-1397; Rev 0; 10/98 EVAALVUAAILTAIOBNLEKIT Serially Controlled, Dual 4x2, Clickless Audio/Video Analog Crosspoint Switches MAX4550/MAX4570 General Description The MAX4550/MAX4570 serial-interface, programmable, dual 4x2 audio/video crosspoint switches are ideal for multimedia applications.
Each device contains two identical crosspoint switch arrays, each with four inputs and two outputs.
To improve off-isolation, use the additional crosspoint inputs SA and SB as shunts.
Each output is selectively programmable for clickless or regular mode operation.
A set of internal resistive voltagedividers supplies DC bias for each output when using AC-coupled inputs.
Additionally, four auxiliary outp...
