LM4903 1 Watt Audio Power Amplifier
General Description
The LM4903 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.

It is capable of delivering 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 LM4903 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 LM4903 features a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with logic low. Additionally, the LM4903 features an internal thermal shutdown protection mechanism. The LM4903 contains advan
