NLAS4783
Triple SPDT 1.0
W
R
ON
Switch
The NLAS4783 is a triple independent ultra−low R
ON
SPDT analog
switch with ENABLE. This device is designed for low operating
voltage, high current switching of speaker output for cell phone
applications. It can switch a balanced stereo output. The NLAS4783
can handle a balanced microphone/speaker/ring−tone generator in a
monophone mode. The device contains a break−before−make feature.
