SoftAMP™ PWM Class D Controller
The ANAGRAM SoftAMP PWM Class D Controller consists of a configurable IP core and reference design architecture optimized for industry standard switching power stages, integrated power MOSFETs, or headphone amplifiers. SoftAMP is designed to deliver an extremely cost effective fully digital audio amplifier solution while providing superior audio quality with 100dB SNR (A) and < 0.05% THD satisfying next-generation high definition audio device requirements. In addition seamless integration with the Q5 Asynchronous Sample Rate Converter IP Core allows support of asynchronous input streams from 8 to 192kHz for more advanced audio processor subsystem architectures, excellent jitter attenuation, and simplified system integration.
