Freescale Turns Up Audio Quality with New Class D Amplifier Solution
Freescale's new Symphony Class D amplifier delivers a high fidelity system solution, featuring innovative digital feedback technology.
Symphony(TM) Class D Offers High Fidelity Audio for Automotive and Consumer Applications
This Class D product extends Freescale's broad Symphony portfolio of semiconductors for audio applications, giving designers a complete, digital audio solution.
Traditionally, Class AB amplifiers have been widely used in the audio industry, but Class D amplifiers were limited to applications such as mini-systems and DVD receivers where high fidelity was a second priority to form factor.
Freescale has changed the playing field with its Class D pulse width modulation (PWM) amplifier, which improves power efficiency from 50 to 90 percent without sacrificing fidelity. This results in lower heat dissipation, allowing more audio channels for a more satisfying listening experience in a dramatically smaller form factor.
