Texas Instruments LM4810
The LM4810 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. The unity-gain stable LM4810 can be configured by external gain-setting resistors. The LM4810 features an externally controlled, activehigh, micropower consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.| Part No. | LM4810 |

DESCRIPTION
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. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
