About this document
LM380 Power Audio Amplifier Overview by Yonatan José Roche Andrade is a document available to read on EtoBox.
- The LM380 is a power audio amplifier intended for consumer applications. It has an internally fixed gain of 50 dB and automatically biases its output to half the supply voltage. - The circuit uses a PNP differential pair input stage and a quasi-complementary emitter-follower output stage. Internal compensation provides wide power bandwidth up to 100 kHz at 2W output. - Applications include basic amplifier configurations, phono amplifiers with volume and tone controls, and circuits achieving the RIAA play
