LM390 1W Battery Operated Audio Power Amplifier
General Description
The LM390 Power Audio Amplifier is optimized for 6V 7 5V
9V operation into low impedance loads The gain is internal-
ly set at 20 to keep the external part count low but the
addition of an external resistor and capacitor between pins
2 and 6 wil increase the gain to any value up to 200 The
inputs are ground referenced while the output is automati-
cally biased to one half the supply voltage
