NLAS4783
Triple SPDT 1 Ohm 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-make feature.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
2. Defined as 10% ON, 90% off duty cycle.
