Product Summary
The lm4881mmx(z81) is a dual audio power amplifier capable of delivering 200 mW of continuous average power into an 8W 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 lm4881mmx(z81) does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. Applications are (1)Headphone Amplifier; (2)Personal Computers; (3)Microphone Preamplifier.
