NLAS4157
SPDT, 1 W RON Switch
The NLAS4157 is a low RON 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 NLAS4157 can handle a balanced
microphone/speaker/ringtone generator in a monophone mode. The
device contains a breakbeforemake (BBM) feature.
