1.2 Watt Stereo Fully Differential Audio Power Amplifier With RF Suppression And Shutdown Low

The LM4928 is an stereo fully differential stereo Audio Power Amplifier primarily designed for demanding applications in mobile phones and other portable Communication devices. It is capable of delivering 1.2 watts of continuous average power to a 8 load with less than 1% distortion (THD+N) from a 5VDC power supply.
Boomer Audio Power Amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4928 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.
The LM4928 features a low-power consumption shutdown mode. To facilitate this, shutdown may be enabled by Logic low. Additionally, the LM4928 features an internal thermal shutdown protection mechanism.
The LM4928 contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn-on and turn-off transitions.
