APPLICATION SUMMARY
- Reference & all mute
When you want to control output bias current of the IP4001, use pin #23 as follows

Fig1. Reference & all mute function
As shown in figure 1,
Pin#23 is a negative input of the comparator,
and the other Input is the 1.0V reference.
If the voltage of the pin#23 falls below 1.0V,
TR Q1 will be turned on and the output bias current
will be shut down
- Mute
When you want to control output bias current of the IP4001, you can also use pin#7 as follows

As shown in figure 2,
Pin#7 is a base input of the TR Q2.
If the voltage of the pin#7 is low or open,
TR Q2 will be turned off and TR Q3 will be turned on,
so the bias current will be shut down by TR Q3.
If the voltage of the pin#7 is high,
the bias circuit operates normally.
