General Description

The LM390 Power Audio Amplifier is optimized for 6V 7 5V 9V operation into low impedance loads The gain is internally 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 automatically biased to one half the supply voltage Y Y Y Y Self-centering output quiescent voltage Variable voltage gain Low distortion Fourteen pin dual-in-line package Applications Y Y Y
