I'm looking for a suitable audio amplifier for my portable and I found this one. It is easy to use, but the datasheet says it has +40 db gain. 40 db is just under normal conversation, so that's much too quiet for a portable.
Is there a difference between 40 db and +40 db gain? How loud would this be in relation to a portable?
