National P/N LM4810 - LM4810 Dual 105mW Headphone Amplifier with Active-High Shutdown Mode
General Description
The LM4810 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average
power into a 16
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 LM4810 does not require bootstrap capacitors or snubber
networks, it is optimally suited for low-power portable systems.
The unity-gain stable LM4810 can be configured by external gain-setting resistors.
The LM4810 features an externally controlled, active-high, micropower consumption shutdown mode, as well
as an internal thermal shutdown protection mechanism.
