Dual SPDT audio switch — 850 mOhm, clickless, 27 MHz
The MAX4762EUB+ is a dual SPDT analog switch with 850 mOhm max on-resistance and 27 MHz bandwidth.
Clickless break-before-make — why it matters for audio
Break-before-make guarantees the old channel opens before the new one closes, so there is no momentary cross-connection. The clickless feature adds a controlled turn-on slew rate that suppresses the DC step that would otherwise produce an audible pop in the speaker or headphones. For a mixer, a headphone amp input selector, or a signal router in a pro-audio rack, this is the difference between a clean transition and a thump that gets amplified.
