LM4809 Datasheet Dual 105mw Headphone Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4809 Dual 105mW Headphone Amplifier with Active-Low Shutdown Mode November 2002 LM4809 Dual 105mW Headphone Amplifier with Active-Low Shutdown.

General Description

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 ponents.

Since the LM4809 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.

Key Features
