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.
