Due to world going to listen to more digital music on mobile media players such as phones and mp3/mp4 players, IMS research says there is going to be more demand for digital audio ICs such as Class D and class G/H amplifiers.

Unit volumes of Class D amplifiers are projected by IMS Research to grow at a CAGR of 35.9% by the end of 2014. The class G or class H amplifier, expected to have a CAGR of almost 64% in unit volumes in the portable space through the end of 2014.

Class D and class H amplifiers are efficiency driven but offer enough signal fidelity to please the ears of average music listener. IC makers who can offer highly efficient amplifiers and also better fidelity in tiny packages will be the choice of audio designers. It can be D, H, J, K or whatever.
