LM4809 Datasheet Document

LM4809 Datasheet Document. Boomer audio power amplifiers were designed specifically to into 32 0.1% (typ) provide high quality output power with a minimal amount of external components. Since the LM4809 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.

Features:

• Active-low shutdown mode
• "Click and Pop" reduction circuitry
• Low shutdown current
• WSON, MSOP, and SOIC Surface Packaging
• No bootstrap capacitors required
• Unity-gain stable

Applications:

• Headphone Amplifier
• Personal Computers
• Microphone Preamplifier
• PDA's

KEY SPECIFICATIONS
