Product Summary

The LM4809LDX is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16Ω load with 0.1% (THD+N) 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. Since the LM4809LDX does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The unity-gain stable LM4809LDX can be configured by external gain-setting resistors. The LM4809LDX features an externally controlled, active-low, micropower consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. Applications are (1)Headphone Amplifier; (2)Personal Computers; (3)Microphone Preamplifier; (4)PDAs.
