Dual SPDT audio switch — 850 mOhm on-resistance, clickless transition
The MAX4762ETB+T is a dual SPDT analog switch with 850 mOhm max on-resistance.
Break-before-make and clickless — why they matter
Break-before-make ensures the switch disconnects the old channel before connecting the new one, preventing momentary shorts between audio sources. The clickless feature suppresses the transient voltage step that would otherwise produce an audible pop at the output. For a dual SPDT part, both channels share the same control logic, so the transition is coordinated across left and right paths.
Package and supply — board-fit notes
The MAX4762ETB+T comes in a 10-TDFN (3x3 mm) package.
