19-1496; Rev 0; 6/99 MAX4548/MAX4549 Serially Controlled, Triple 3x2 Audio/Video Crosspoint Switches General .
The MAX4548/MAX4549 serial-interface, programmable, triple 3x2 audio/video crosspoint switches are ideal for multimedia applications.
Features
* o Selectable Soft-Switching Mode for “Clickless” Audio Operation
o 22Ω Typical On-Resistance (+5V Supply) o 5Ω Typical On-Resistance Matching Between
Channels
o 2Ω Typical On-Resistance Flatness o Audio Performance
-85dB Off-Isolation at 20kHz -85dB Crosstalk at 20kHz 0.07% THD with 600Ω Load o Vide
Applications
* The devices include three crosspoint switch matrices, each containing three inputs and two outputs. To improve off-isolation, each switch matrix has a shunt input and each output is selectively programmable for clickless or regular-mode operation. A selectable set of internal resistive voltage divi
