General Description
The LM4915 is a pseudo-differential audio power amplifier primarily designed for demanding applications in mobile phones and other portable audio device applications with mono headphones.
Key Features
- a low-power consumption shutdown mode. To facilitate this, Shutdown may be enabled by driving the shutdown pin low. Additionally, the LM4915 features an internal thermal shutdown protection mechanism. The LM4915 contains advanced pop & click circuitry which virtually eliminates noises which would otherwise occur during turn-on and turn-off transitions. The LM4915 has an internally fixed gain of 6dB. Key Specifications n n n n Improved PSRR at 217Hz and 1kHz 75dB (typ) Power Output at 5.0V & 1%.
