The company offers digital audio products, including converters; video products that include A/V interface, amps and switches, encoders and decoders, and analog front ends; sensor products; communications products, such as analog cordless telephone and two-way radio; and clock devices, including single and multi-clock clock generators, spread spectrum, and clock buffers. It also offers power devices, such as white LED drivers, DC-DC converters, active noise filters, regulators, motor drivers, video amplifiers, and pin diodes; audio amplifiers; and touchscreen controllers. The company provides application solutions, such as pro audio, consumer audio/video, portable audio, USB audio, set-top boxes and DTV, automotive, PC and peripherals, and magnetic sensors. It sells its products through sales representatives and distributors in Japan, Asia, Europe, and China. The company was founded in 1995 and is based in San Jose, California. AKM Semiconductor, Inc. operates as a subsidiary of Asahi Kasei Microsystems Co., Ltd.
The Velvet Sound brand was launched in 2014, bringing with it a new-generation chip architecture. The third generation Premium DAC, the Verita AK4490, employed AKM's enhanced low-distortion technology to achieve 120dB SNR, and an industry-best voltage output performance of -112dB THD+N - the world's best distortion characteristics and world's lowest out-of-band noise. In 2019, AKM introduced the flagship Verita AK4499, its first current-output DAC and AKM's highest-performing DAC, with 140dB SNR and -124dB THD+N. For over three decades, AKM shipped billions of these components to more than 2500 manufacturers in high-end audio, consumer electronics, automotive, professional audio, studio equipment and musical instruments. The Velvet Sound audio ICs in particular, reflect the company's expertise in low distortion and low noise and are regarded as a "core technology" in ADCs, DACs, and audio CODECs for very high-quality designs.
You may be surprised to find AKM's Hall sensors in such products as these! Hall sensors are used in familiar products such as air conditioners, washing machines, and smartphones. Here we will explain why AKM's Hall sensors are widely chosen by many people. AKM's Hall effect ICs and Linear Hall effect ICs use high-sensitivity compound semiconductor Hall elements for the sensor. This eliminates the need for complex processing within the control ICs, achieving the high response speed. AKM's Hall sensors respond to such needs as the need to obtain output that follows the quick movement of the magnet.
Audio & Voice DSP:
For more than 20 years, AKM has provided its own audio and voice processor products and software to the automotive sector, which has stringent requirements. How have our products been so trusted to date? Here, we will uncover the secrecy as well as the history of AKM sounds. AKM has held a key role in the transition to high-quality digital audio since it released its first-generation delta-sigma modulation analog-to-digital converters (ADC) in 1987. AKM consistently improved conversion resolution, from the first generation of 16-bit devices to 18-, 24-, and 32-bit ADCs, and has increased sampling frequencies from 48kHz to 768kHz, being key to many great-sounding consumer and professional digital audio designs.
