LM4809 Double 105MW Active low -level headset amplifier shutdown mode
General description
LM4809 is a dual audio power amplifier, which can transport 105MW continuous average power from 5V power input 0.1%(THD+N) per channel. Boomer audio power amplifier is specifically for the least external component. Because LM4809 does not need to be raised by a capacitor or a buffer network, it is suitable for low -power portable systems. The stable LM4809 of the unit gain can set the resistor from the external configuration gain. LM4809 is characterized by external control, low level, micro -power closing mode, and internal heat shutdown protection mechanism.
Main specifications
105MW NTD+N when the continuous average power of 1kHz becomes 16Ω0.1%(typical value)
70MW continuous average power of 1kHz at 1kHz. N ThD+N becomes 32Ω0.1%(typical value)
Turn off the current 0.4 Wei'an (typical value)
