LM4809 Datasheet (National Semiconductor) - Dual 105mW Headphone Amplifier

LM4809, Dual 105mW Headphone Amplifier

The LM4809 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16Ω load with 0.1% (THD+N) from a 5V power supply.

Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external com
