Application Information
1. REFERENCE INPUT & MUTE CIRCUITS
Pin 23 can be used as a reference input terminal and a mute terminal.
Reference input circuit
An external allowable reference voltage to pin 23 is normally 2.5V.
In general conditions, pin 23 is used as the reference input terminal and is good to be used between about
2V-6.5V.
Mute circuit
The following represents the conditions when the external mute is permitted to pin 23.
