stereo class-D audio power amplifier

It has two channels of auxiliary PWM output and three channels of auxiliary digital audio output. NSP-2100A includes essential preprocessor features like full channel mixer, adaptive gain control, de-emphasis, 3D surround, 5band graphic EQ, general purpose biquad filter blocks, delay line and volume control & dynamic range compression. Using external memory, Lip-sync delay compensation can be implemented. NeoFidelity's patent filed functional block called SFACS(Sampling Frequency Adaptive Coefficient Scaling) and world- unique floating point operation scheme eliminate audio performance degradation problem in the conven- tional asynchronous SRC system and are optimized for preserving audio quality.
