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 snub ber networks, it is optimally suited for low-power portable systems.
