Speaker / Headphone Amplifier Series

FAQ

What is BTL output method?

It is the abbreviation of Bridge Tied Load.
It reverses the speaker both terminals to connect by using two amplifier circuits compared with a usual single amplifier. If without output coupling capacitor,it may has an advantage that output electric power quadruples.

Is the input form a differential input type? Is it a single input type?

Please choose according to customer's system configuration.
In case of differential input form,BH7826FVM can be used, and in case of single input form, BH7824FVM/BD7830NUV can be used

Can bass play with a small and thin speaker?

Because bass boost (for low region enhancement) circuit is built into BH7881EFV, an enough bass can be played with a small and thin speaker.
