Functional Description
Power Supply Range
This IC is designed to operate on single supply, shown by table 1.

Power Supply Range
Single Supply
9.5V to 15.0V
Reference Voltage
So little is the current drivability of AC reference (Vref) that the Vref voltage may be altered by A/B
switching of PB-EQ.
Provided it causes you anxiety, please use the constant 1/2 V
CC
voltage circuit, for example, figure 1.
In addition, this IC has a capacitor charger for Vref pin.
