نظرة عامة على المنتج
The LM386N-4/NOPB is a low voltage audio power amplifier manufactured by Texas Instruments. It is designed for battery-powered consumer audio applications, delivering 1W output into an 8-ohm load from a 16V supply. The device operates over a wide supply voltage range of 5V to 18V with very low quiescent current drain, making it ideal for portable and battery-operated audio systems.
