Switch
The NLAS5123 is a low R
ON
SPDT analog switch. 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 NLAS5123 can handle a balanced microphone/
speaker/ringtone generator in a monophone mode. The device
contains a break−before−make (BBM) feature.
