.. LM4947 Mono Class D and Stereo Audio Subsystem with OCL Headphone Amplifier and National 3D October 2006 LM4947 Mono Class D and Stereo Audio Subsystem with OCL Headphone Amplifier and National 3D General Description The LM4947 is an audio subsystem capable of efficiently delivering 500mW (Class D operation) of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N, 37mW (Class AB operation) power channel of continuous average power into stereo 32Ω single-ended (SE) loads with 1% THD+N, or an output capacitor-less (OCL) configuration with identical specification as the SE configuration, from a 3.3V power supply. The LM4947 has six input...
