Frequently Asked Questions
What materials are required for mounting the IC?
Mounting requires a PCB of glass epoxy material (70mm×70mm×1.6mm).
How is power efficiency affected by ambient temperature?
PreVCC should be kept at least 4.3 V, and PowVCC should meet a minimum of 4.3 V.
How do I prevent oscillation when connecting capacitive loads to the amplifier output?
Insert a series resistance between the output and capacitance load, considering frequency characteristics.
