General Description

The LM4881 is a dual audio power amplifier capable of delivering 200 mW of continuous average power into an 8Ω load with 0.1% (THD) from 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 LM4881 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.

Key Features

an externally controlled, low power consumption shutdown mode which is virtually clickless and popless, as well as an internal thermal shutdown protection mechanism. The unity-gain stable LM4881 can be configured by external gain-setting resistors. Key Specifications n THD at 1 kHz at 125 mW continuous average output power into 8Ω n THD at 1 kHz at 75 mW continuous average output power into 32Ω n Output power at 10% THD+N at 1 kHz into 8Ω n Shutdown Current 0.1% (max) 0.02% (typ) 300 mW (typ) 0.
