According to Databeans, the Class D amplifier
market is expected to reach $347 million (USD) this year and is projected to grow 11 percent (CAGR) over the next five years, well over the industry average for the audio market.
s (Nasdaq:CRUS) new CS4525 is an innovative, highly integrated single-chip Class D Amplifier
for the rapidly expanding global flat-panel digital television market.
Freescale's Class D amplifier
with its advanced digital feedback is a real breakthrough and allows OEMs to achieve the highest quality performance, in a smaller form factor and still benefit from the power savings of a Class D amplifier
With more than 20 issued and 20 pending patents, JAM has redefined Class D amplifiers
Other Class D amplifiers
can improve efficiency, but at higher cost, greater complexity and lower audio quality," explained Larry Kirn, JAM CTO.
Wolfson believes that low cost high efficiency Class D amplifiers
are about to have a major impact on the design of domestic, portable and in-car audio and ease of design and support will be key to ensuring short times to market for new products using this exciting technology.

Findings verified that JamTech's technology exceeds measurements typically achieved by traditional analog pulse width modulation (PWM) Class D amplifiers
and delta-sigma PWM digital amplifiers for both absolute dynamic range and spectral noise floor, two important measures of fidelity in digital audio systems.
The JM2020, features a monolithic design integrating both the modulator and power stage into a single chip, and delivers best in class audio fidelity at a price comparable to traditional Class D amplifiers
and newer delta-sigma PWM digital amplifiers.
Performance results verify that JamTech's technology exceeds measurements typically achieved by traditional analog pulse width modulation (PWM) Class D amplifiers
and delta-sigma PWM digital amplifiers for both range of linearity and spectral noise floor, two important measures of fidelity in digital audio systems.
