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.
