LM4947 Mono Class D and Stereo Audio Sub-System 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 8 bridged-tied load (BTL) with 1% THD +N, 37mW (Class AB operation) power channel of continuous average power into stereo 32 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 channels: one pair for a two-channel stereo signal, the second pair for a secondary two-channel stereo input, and the third pair for a differential single-channel mono input. Additionally, the two sets of stereo inputs may be configured as a single stereo differential input (differential left and differential right). The LM
