A class D audio amplifier, also known as switching or PWM amplifier, is widely used to reduce power loss in output devices. With digital or analog inputs, the class D audio amplifier market’s growth is primarily supplemented by the growing popularity of electric vehicles and applications in consumer electronics, especially smartphones.
Consumer electronics have become an integral part of an individual’s life, witnessing significant developments each year. Audio class D has attained significant demand from consumer electronics, ranging from mobile phones to televisions to home theatre systems. In this regard, the amplifiers integrated into smartphones are compact and highly efficient, resulting in superior sound quality.
Additionally, given the shrinking space for audio systems inside speakers and smartphones, numerous companies have plugged signal processing directly into amplifier ICs. For instance, Cirrus Logic, a leading supplier of audio amplifiers in smartphones, has integrated DSPs into class D devices, introducing its first 55-nanometer smart audio amplifier.
Our estimates indicate the global class D audio amplifier market to reap revenue worth $5176.17 million in 2028, advancing at a CAGR of 10.56% over the forecast period 2022-2028.
Owing to the evolution of new technologies, the class D audio amplifier market is expected to witness significant growth in the Asia-Pacific countries. Several leading electronic manufacturers are developing products, owing to the low cost of shipments and final products. Moreover, favorable government initiatives have considerably contributed to the regional market’s growth. For instance, the establishment of China’s Audio and Video Coding Standard Workgroup has led companies like Alibaba to expand footings and innovate in the market.
Over the years, artificial intelligence and machine learning technologies have gained sizable attention across industries. In fact, AI and ML applications have grown significantly, from thermostats to smart speakers. Over the years, RF engineers have strived to enhance amplifier’s merits, such as efficiency, bandwidth, and linearity. In this regard, AI and ML have enhanced the potential application of class D audio amplifiers in audio systems across consumer electronics and automotive. This has ultimately led prominent companies to unveil new products to compete in the technologically advanced market space. For instance, Texas Instruments launched three digital-input class D audio amplifiers that include real-time protection and new modulation schemes to reduce board space and material cost.
Internet of Things (IoT) has emerged as the most sought-after technology trend in recent years. The growing popularity of IoT-enabled devices will surge the class D audio amplifier adoption over the forecast period, thus fueling market growth. Further, it is imperative to design an efficient wireless transmitter with a cost-efficient class D amplifier to satisfy the multi-standard demands. Hence, class D amplifiers for battery-operated IoT devices must be linear across multiple power levels to ensure efficient data interchange. NXP Semiconductors, for instance, launched the TFA8200 BTL audio class D amplifier comprising digital inputs for portable applications.
Class-D amplifiers are widely adopted in vehicles, owing to benefits such as high efficiency, less power consumption, and small size. Moreover, high power potential, approximately 400-500 W, in a small package has proved the worth of these amplifiers in automotive. The automotive segment is estimated to witness the fastest growth over the forecast period. The segment’s robust growth is attributed to the growing adoption of radio, sound systems, hands-free Bluetooth phones, and voice-response, resulting in high demand for audio amplifiers. PMP11769 automotive external audio amplifier reference by Texas Instruments is one such example that includes audio amplifier modules.
The consumer electronics segment dominates the market and is expected to continue its stronghold by 2028. In smartphones, class D amplifiers play a crucial role in ensuring high power and fine-tuning the audio system. In recent years, the growth of mobile gaming and streaming platforms has surged the demand for better sound quality. As a result, the high adoption of consumer electronics has prompted class D amplifiers to have witnessed high volume sales in the past few years.
Our estimates indicate smart TV ownership to rise by around 51% by 2026. The growing sales of smart devices will create a profitable opportunity for class D amplifiers. Besides, the high demand for Bluetooth, Wifi, and LCD screen in automotive will also push its demand to a large extent. Hence, consumer electronics and automotive industries are estimated to remain a major focus point for manufacturers, contributing significant revenue share in the class D audio amplifier market.
Asia-Pacific region is expected to grow with the highest CAGR. The growing population and the presence of leading electronic manufacturers are the key advantages supporting the fastest growth of the regional market.
Our estimates indicate the global class D audio amplifier market will generate revenue worth $5176.17 million by 2028.
