What is full power mode, 3/4 power mode, & 1/2 power mode?
When reading the datasheet of EL8108，
In page 4, typical performance curves,
there are diagrams for full power mode, 3/4 power mode, & 1/2 power mode.
What is the definition for xx power mode?
Are they something related with the power efficiency , like different efficency for Class A, class D amplifiers?

Re: What is full power mode, 3/4 power mode, & 1/2 power mode?
The data sheet doesn't say but I would assume it refers to the amount of load placed on the output. This to some degree changes the internal feedback and hence gain/phase response of the amplifier. Full power I would guess is the measurement under maximim load, 1/2 power at half the maximum load and so on.
You can't program the power and the amplifier can't change it's mode of operation so it must be a reference to how hard you are loading it.
PLEASE - no friends requests or private emails, I simply don't have time to reply to them all.
It's better to share your questions and answers on Edaboard so we can all benefit from each others experiences.
