LM388 - LM388 1.5W Audio Power Amplifier

This page provides the datasheet information for the LM388, a member of the LM3 LM388 1.5W Audio Power Amplifier family.

Datasheet Summary

Description

The LM388 is an audio amplifier designed for use in medium power consumer applications The gain is internally set to 20 to keep external part count low but the addition of an external resistor and capacitor between pins 2 and 6 will increase the gain to any value up to 200 The inputs are ground refe
