The forward voltage gain is usually high at least 40 db. Electret microphones are simple little devices. If the forward gain is part of a feedback loop the overall loop gain will also be high.
These amplifier ics combine circuit design manufacturing process innovation and applications expertise to create products that simplify signal conditioning design.
It provides a surprising amount of sound power when played through a large speaker and maybe run without heatsinks on the transistors though you should experiment with it a bit before deciding to forego heat sinks as the power dissipation varies according to the type of speaker used. This amplifier circuit also works well in amplifying line level audio signals from high quality modular stereo components. Simple analog amplifiers step 1. Amplifiers from analog devices deliver both high performance and high value.
