Note 1:
On rising VDD, the voltage at which the device internal Reset will get released.
2:
On dropping VDD, the voltage at which the internal Reset circuit will reset. On dropping VDD, it is recommended to bring the VDD below this voltage to get a proper Reset.
3:
Before using the SHDN pin, the device should first be powered up. Once the device is fully powered up, then the shut down pin can be used.
4:
µVPP is six times the value of µVRMS.
