Serially Controlled, Clickless Audio/Video Switches MAX4562/MAX4563 General Description Features
The MAX4562/MAX4563 serial-interface controlled ♦
Selectable Soft-Switching Mode for “Clickless”
switches are ideal for multimedia applications. Each

crosstalk at 10MHz is -55dB. Both devices feature
-85dB Off-Isolation at 20kHz
“clickless” mode operation for audio applications.
-85dB Crosstalk at 20kHz
The MAX4562/MAX4563 contain two normally open sin-
-0.007% THD
gle-pole/double-throw (SPDT) switches and two normal- ly open single-pole/single-throw (SPST) switches. The ♦
