7. Junction temperature detecting pin 23
Using temperature characteristic of a band gap circuit and in proportion to junction temperature, pin 23
DC voltage: V23 rises at about +5 mV/°C temperature characteristic. The relation between V23 at Tj = 25°C
and V23x at Tj = x°C is decided by the following expression :
In deciding a heat sink size, a junction temperature can be easily made clear by measuring voltage at this
pin while a backside temperature of IC was so far measured using a thermocouple type thermometer.

8. Cross talk
The cross talk characteristics of the IC is not good between OUT1 and 2, OUT3 and 4.
So we recommend to use by below method.
OUT1, 2
OUT3, 4
L-ch (or R-ch)
R-ch (or L-ch)
And, please refer to below table in case of applying the AUX. IN because it is out to OUT1 and 4.
