LM390 1W Battery Operated Audio Power Amplifier
General Description
The LM390 Power Audio Amplifieris optimizedfor6V, 7.5V, operationintolow impedance loads.The gainis internal-setat20to keepthe external part count low,butthe
additionofan external resistorand capacitor between pinsand6wil increasethe gaintoany valueupto 200.The
inputsare ground referenced whilethe outputis automati-
cally biasedtoonehalfthe supply voltage.
Features Battery operation 1W output power Minimum external parts Excellent supply rejection Ground referenced input Self-centering output quiescent voltage Variable voltage gain Low distortion Fourteenpin dual-in-line package
Applications AM-FM radio amplifiers Portable tape player amplifiers IntercomsTV sound systems Lamp drivers Line drivers Ultrasonic drivers Small servo drivers Power converters
