4.
Power Switch
As long as the power switch is not connected to “H” level, the IC does not operate. If it malfunctions due
to external noise, however, it is recommended to connect a pull-down resistor externally (the power switch
is set to be highly sensitive).
5.
Threshold Voltages of Switches
6.
These capacitors which prevent oscillation of the power amplifier, and are between
the Vref and VCC-GND must have a small temperature coefficient and outstanding
frequency characteristics.
