LM4880 - Dual 200 mW Audio Power Amplifier with Shutdown Mode

Features • No bootstrap capacitors or snubber circuits are necessary • Small Outline (SO) and DIP packaging • Unity-gain stable • External gain configuration capability Key Specification • THD+N at 1kHz at 200mW continuous average output power into 8: 0.1% (max) • THD+N at 1kHz at 85mW continuous average output power into 32: 0.1% (typ) • Output power at 10% THD+N at 1kHz into 8: 325mW (typ) • Shutdown current: 0.7µA (typ) • 2.7V to 5.5V supply voltage range General Description The LM4880 is a dual audio power amplifier capable of delivering typically 250mW per channel of continuous average power to an 8 load with 0.1% THD+N using a 5V power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging. Since the LM4880 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The LM4880 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable LM4880 can be configured by external gain-setting resistors. . Applications • Headphone Amplifier • Personal Computers • CD-ROM Players

General Description

The LM4880 is a dual audio power amplifier capable of delivering typically 250mW per channel of continuous average power to an 8 load with 0.1% THD+N using a 5V power supply.

Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging.

Since the LM4880 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.

The LM4880 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.

The unity-gain stable LM4880 can be configured by external gain-setting resistors.
