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
Features
Y Battery operation
Y 1W output power
Y Minimum external parts
Y Excellent supply rejection
Y Ground referenced input
Y Self-centering output quiescent voltage
Y Variable voltage gain
Y Low distortion
Y Fourteen pin dual-in-line package
Applications
Y AM-FM radio amplifiers
Y Portable tape player amplifiers
Y Intercoms
Y TV sound systems
Y Lamp drivers
Y Line drivers
Y Ultrasonic drivers
Y Small servo drivers
Y Power converters
