NLAS4157
SPDT, 1 W RON Switch
The NLAS4157 is a low R SPDT analog switch. This device is
ON
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 break−before−make (BBM) 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.

5. Flatness is defined as the difference between the maximum and minimum value of On Resistance over the specified range of conditions.
6. Guaranteed by Design.
7. This parameter is guaranteed by design but not tested. The bus switch contributes no propagation delay other than the RC delay of the On
Resistance of the switch and the 50 pF load capacitance, when driven by an ideal voltage source (zero output impedance).
