When it comes to high-quality digital-to-analog converters (DACs), one name that often comes to mind is AKM (Asahi Kasei Microdevices). Their DAC chips have been widely adopted in various industries, from professional audio equipment to consumer electronics. However, have you ever wondered who exactly makes these exceptional AKM DAC chips? In this article, we’ll delve into the history of AKM, explore their role in the DAC market, and attempt to answer the question on everyone’s mind.
A Brief History of AKM and DAC Development
Asahi Kasei Corporation, the parent company of AKM, was founded in 1922 in Japan as a textile manufacturer. Over the years, the company diversified and expanded into various fields, including electronics. In the 1970s, Asahi Kasei began developing semiconductor products, including microcontrollers, memory devices, and analog ICs. In 1988, they established Asahi Kasei Microdevices Corporation (AKM) as a subsidiary focused on developing and manufacturing semiconductor devices.
In the 1990s, AKM began developing digital-to-analog converters (DACs), which quickly gained popularity in the audio industry. Their DAC chips were highly regarded for their exceptional sound quality, low noise, and high signal-to-noise ratio. As the demand for high-quality audio increased, AKM’s DAC chips became the go-to choice for many manufacturers.
The Rise of AKM in the DAC Market
AKM’s entry into the DAC market was a game-changer. Their innovative designs and manufacturing techniques allowed them to produce high-performance DACs at a relatively low cost. This made high-quality audio more accessible to a wider range of consumers. As a result, AKM’s DAC chips became ubiquitous in the audio industry, finding their way into everything from professional audio equipment to home hi-fi systems.
One of the key factors contributing to AKM’s success was their ability to develop DAC chips with high dynamic range and low distortion. This enabled audio equipment manufacturers to produce devices that could accurately reproduce the full range of human hearing, from the softest whispers to the loudest crescendos.
The AK4490 Series: A Breakthrough in DAC Technology
In 2014, AKM released the AK4490 series of DAC chips, which marked a significant breakthrough in DAC technology. These chips boasted an industry-leading 120 dB signal-to-noise ratio, making them the new standard for high-fidelity audio. The AK4490 series quickly became the gold standard for DAC chips, and manufacturers scrambled to integrate them into their products.
The AKM DAC Chip Manufacturing Process
So, who makes AKM DAC chips? The answer lies in AKM’s manufacturing process. While AKM designs and develops the DAC chips, they do not manufacture them in-house. Instead, they outsource production to various contract manufacturers, also known as foundries.
AKM partners with these foundries to produce their DAC chips using advanced semiconductor manufacturing technologies, such as CMOS (Complementary Metal-Oxide-Semiconductor) and BiCMOS (Bipolar CMOS). These foundries, often located in Asia, possess the necessary expertise and equipment to manufacture high-quality DAC chips at scale.
Once the DAC chips are manufactured, AKM tests and validates them to ensure they meet their rigorous quality standards. This includes various tests, such as audio performance evaluation, temperature testing, and reliability testing.
The Role of Taiwan Semiconductor Manufacturing Company (TSMC)
One of the primary foundries used by AKM is Taiwan Semiconductor Manufacturing Company (TSMC). TSMC is the world’s largest independent semiconductor foundry, with a reputation for producing high-quality, high-performance chips. AKM has a long-standing partnership with TSMC, which enables them to leverage TSMC’s advanced manufacturing technologies to produce their DAC chips.
Other Contract Manufacturers
In addition to TSMC, AKM also partners with other contract manufacturers, such as Samsung Electronics, GlobalFoundries, and United Microelectronics Corporation (UMC). These foundries provide AKM with the necessary capacity and expertise to meet the growing demand for their DAC chips.
The Impact of the 2020 Fire on AKM’s DAC Chip Supply
In October 2020, a devastating fire broke out at AKM’s Nobeoka, Japan, plant, which primarily produced DAC chips. The fire caused significant damage to the facility, resulting in a temporary halt in production. This event sent shockwaves through the audio industry, as manufacturers reliant on AKM’s DAC chips scrambled to find alternative suppliers.
The fire highlighted the fragility of the global supply chain and the importance of diversification. Many manufacturers were forced to explore alternative DAC chip sources, such as Texas Instruments, Analog Devices, and ESS Technology. While AKM worked to restore production, the industry was forced to adapt to a new reality.
The Recovery Efforts and Lessons Learned
In the aftermath of the fire, AKM implemented measures to mitigate the disruption and ensure a stable supply of DAC chips. They worked closely with their foundry partners to increase production capacity and implemented contingency plans to prevent similar disruptions in the future.
The incident served as a wake-up call for the industry, emphasizing the need for diversification and risk management. Manufacturers realized the importance of having multiple supply chain options and contingency plans in place to minimize the impact of unexpected events.
