The Maxim Integrated MAX4745ELB+T is a dual SPDT analog switch designed for audio signal routing. Its 950mOhm maximum on-resistance keeps insertion loss low in the audio band.
Housed in a 10-WFDFN package (2x2 mm body), the MAX4745ELB+T saves board area on dense mixed-signal PCBs. The supplier device package is 10-µDFN (2x2). Surface-mount assembly is standard.
The maximum on-resistance is 950mOhm across the specified supply range. This low RON keeps insertion loss minimal in audio signal paths.
Break-before-make ensures that the switch opens one path before closing the other, preventing momentary short circuits between signal sources. Clickless operation suppresses the audible pop that can occur during switching, which is critical for audio routing applications.
