Switch
The NLAS9051 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 NLAS9051 can handle a balanced microphone/
speaker/ringtone generator in a monophone mode. The device
contains a break−before−make (BBM) feature.

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).
