NLAS4157 D

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 break−before−make (BBM) feature.

2. Measured by the voltage drop between A and B pins at the indicated current through the switch. On Resistance is determined by the lower
of the voltages on the two (A or B Ports).
3. Parameter is characterized but not tested in production.
4. DRON = RON max − RON min measured at identical VCC, temperature and voltage levels.
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).
