About Sanyo Semiconductor (a member company of ON Semiconductor)
Sanyo Semiconductor Co., Ltd. (a member company of ON Semiconductor) is a semiconductor manufacturing company with excellent power device technology, such as small packaging technology, high energy efficiency switching technology, high density packaging technology, etc., and the world's YI flow simulation technology. Several simulation-related assets include a wide range of process technology, simulation design technology, skilled simulation engineers, and specially designed and manufactured excellent energy-saving and environmentally friendly devices, such as hybrid integrated circuits for inverters. The core devices of Sanyo Semiconductor include discrete circuits, general-purpose analog large-scale integrated circuits, ASSP and hybrid integrated circuits, which are widely used in various products such as personal computers, printers, cable TV, mobile phones, audio-visual equipment, game equipment, car audio Systems and air conditioning.
Sanyo STK is commonly known as Sanyo Thick Film. Under the control of the adjusted sound and high-precision semiconductor process production process, it is not a level that ordinary amateur DIY players can achieve. In addition to better sound field and resolution, the low-frequency strength is much stronger, which is the difference between professional athletes and ordinary players These thick-film circuits are always customized products for large-scale audio manufacturers. Many well-known factories in the early days used them to make power amplifiers, such as K + H, Sony SONY, Panasonic PANSONIC, Kenwood KENWOOD, JV JVC, Shanshui SANSUI, Sharp SHARP, Pioneer PIONEER, Aiwa AIWA, etc. Almost all Japanese audio It has been selected by manufacturers and has been in use for more than two decades. It has influenced a whole generation. It is also the sound with strong brand of the times that we have heard for a whole generation when we were young. It is unforgettable every time it sounds. Sanyo's company specializing in the production of power amplifier modules was later acquired by ON Semiconductor of the United States. After the acquisition, it integrated Sanyo's traditional processes, coupled with ON's unique design, the later products are more outstanding, and it is still used by large companies in the United States. , Such as BOSE, such as the European Genelec
I was fortunate to come across the brand new stock of Sanyo SANYO's later power amplifier module STK496-090, which is the sound of the classic Sanyo. Unfortunately, in the later period, with the vigorous development of the Internet and the large-scale popularization of various portable devices (especially large-screen touch-screen mobile phones), many people have slowly forgotten these high-performance desktop devices. Those formerly well-known audio manufacturers had to change the direction of their products one after another, making these customized products dust-covered in the warehouse of the original SANYO packaging factory in the Philippines, and stayed for more than ten years.
After the test, I found that this module still has relatively large potential. According to the official circuit test, the sound is quite satisfactory. Under the recommended working voltage AC double 35V voltage, its output power is 100WX2 @ 6 (THD = 0.05%). The working voltage is recommended to be plus or minus 45V, and the maximum working voltage should not exceed plus or minus 52V. (According to official data)
