1.1w Audio Power Amplifier With Shutdown Mode - National Semiconductor

The LM4870 is a bridge-connected Audio Power Amplifier ca- pable of delivering 1.1W of continuous average power to an 8 load with less than 0.5%THD+N over the Audio spectrum from a 5V power supply. Boomer Audio Power Amplifiers were designed specifically to provide high quality output power with a minimal number of external components. Since the LM4870 does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is optimally suited for low-power portable sys- tems. The LM4870 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. It also includes two head- phone control inputs and a Headphone sense output for ex- ternal monitoring. The LM4870 is unity-gain stable and the gain is set using external resistors.
