APPLICATION SUMMARY
- All mute function using the REF pin

When the all mute function is required, you can use the reference pin as follows;
Pin 23
Mute
Above
1.0V
off
Below 1.0V
on
- All mute function using the Mute pin

All mute function can be also obtained using the MUTE pin as follows;
Pin 7
Mute
High
off
Low
on
Fig. 1. All mute function using the reference pin
Fig. 2. All mute function using the MUTE pin
Muting all channel drivers can be obtained using the
REF (signal reference) pin. The simplified schematic
diagram for reference all mute function is shown in
Fig.1. When the input voltage of the signal reference
pin (pin23) is below 1.0V, the comparator turns Q1 on
and the bias currents of all output drivers are shut
down.
As we can see in Fig. 2, if the voltage of the pin7
becomes low (below 0.5V) or open, the bias currents
for all output drivers are shut down.
On the contrary, when the voltage of the pin7 becomes
high (above 2.0V), the drivers operate normally.

The IP4001S has a thermal protection against the
abnormal operation. When the junction temperature
rises above 175
O
C, and channel drivers are muted.
This makes the junction temperature be continuously
decreased.
When the junction temperature falls below 150
O
C, all
channel operature again.
