General Description
The LM4906 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.
It is capable of delivering 1W of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a +5V power supply.
Key Features
- a low -power consumption shutdown mode (the part is enabled by pulling the SD pin high). Additionally, the LM4906 features an internal thermal shutdown protection mechanism.
