Single Supply
9.5 V to 15.0 V
Reference Voltage
As AC reference (Vref) of this IC has not a current drivability, Vref fluctuates by A/B switching of PB-EQ.
Provided it causes you anxiety, please supply 7 pin with approximate 1/2 V
CC
voltage.
For example, a suitable circuit is shown by figure 1.
This IC has a capacitor charger for the Vref, indicated to the pin interface circuit figure.
