A Class D audio amplifier integrated circuit (IC) is a switching or pulse width modulation (PWM) amplifier.Class D amplifiers are designed to keep audio signals digital from input to output, conserving the detail of the signal and allowing higher efficiency than its predecessors such as Class A, B and AB devices.

These audio amplifiers can achieve energy efficiencies above 90% by eliminating the use of linear gain devices and other analog components, which drive up the power dissipation of linear amplifiers. Higher efficiency results in low thermal dissipation and thus dissipates less power. Class D amplifiers are highly power efficient; they require a smaller heat sink and a smaller power supply, which
has made Class D audio amplifiers popular in applications such as mobile phones, handheld audio devices, speakers, portable home theaters, TV, and automotive infotainment systems. However, Class D audio amplifiers do have some limitations. As the space for audio systems inside applications such speakers, smartphones and other portable audio devices has been shrinking, this has caused the problem of electromagnetic interference in Class D audio devices, which can degrade audio performance compared to linear amplifiers. As a result, manufacturers have started to offer smart audio amplifiers that integrate digital signal processors (DSPs) and Class D devices to enhance audio while preventing overheating. They also aim to prevent the amplifier from supplying too much power to the physical speaker’s driver, which can lead to thermal failures.

The global market for Class D audio amplifier solutions was valued at REDACTED in 2019 and is forecast to reach REDACTED by 2025, growing at a CAGR of REDACTED during the forecast period.Some of the majordrivers for the growth of the Class D audio amplifier market include growth in demand for smart consumer electronics, an increasing trend towards stereo audio in portable audio devices, and growing demand for vehicle infotainment systems in automobiles.

The rising penetration of 5G smartphones will provide a major opportunity for the market. However, the high cost of integrating an LC filter can act as a challenge for the growth of the Class D audio amplifier market.

In this report, the global Class D audio amplifier market has been segmented based on device, speaker channel, audio input type, and geography.
