LM380N-8

TEXAS INSTRUMENTS  LM380N-8  音频功率放大器, 1通道, 2.5 W, 10V 至 22V, DIP, 8 引脚

DESCRIPON

The LM380 is a power audio amplifier for consumer applications. In order to hold system cost to a minimum, gain is internally fixed at 34 dB. A unique input stage allows ground referenced input signals. The output automatically self-centers to one-half the supply voltage.

The output is short circuit proof with internal thermal limiting. The package outline is standard dual-in-line. The LM380N uses a copper lead frame. The center three pins on either side comprise a heat sink. This makes the device easy to use in standard PC layouts.
