1.1 Watt Audio Power Amplifier

The LM4879 is an Audio Power Amplifier primarily designed for demanding applications in mobile phones and other por- table Communication device applications. It is capable of delivering 1.1 watt of continuous average power to an 8 BTL 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 LM4879 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for lower-power portable applications where minimal space and power consumption are primary require- ments. The LM4879 features a low-power consumption global shut- down mode, which is achieved by driving the shutdown pin with Logic low. Additionally, the LM4879 features an internal thermal shutdown protection mechanism. The LM4879 contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn-on and turn-off transitions. The LM4879 is unity-gain stable and CAN be configured by external gain-setting resistors. By National Semiconductor Corporation
