LM388 1.5W Audio Power Amplifier
General Description
The LM388isan audioamplifierdesignedforusein medium
power consumer applications. The gainis internallysettoto keep external part count low,butthe additionofan
external resistor and capacitor between pins2and6will
increasethe gaintoany valueupto 200.
The inputsare ground referenced whilethe outputis auto-
matically biasedtoonehalfthe supply voltage.
Features Minimum external parts Wide supply voltage range Excellent supply rejection Ground referenced input Self-centering output quiescent voltage Variable voltage gain Low distortion Fourteenpin dual-in-line package Low voltage operation,4V
Applications AM-FM radio amplifiers Portable tape player amplifiers IntercomsTV sound systems Lamp drivers Line drivers Ultrasonic drivers Small servo drivers Power converters
