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, and the world&x27;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 conditioners.



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 completely the difference between professional athletes and ordinary players These thick-film circuits are always customized products for large-scale audio manufacturers. Many famous 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, and it is also the sound of the 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&x27;s company specializing in the production of power amplifier modules was later acquired by ON Semiconductor of the United States. After the acquisition, Sanyo&x27;s traditional technology was integrated, and the unique design of ON, the later products are more outstanding, and they are still used by large companies in the United States. , Such as BOSE, such as the European Genelec

Fortunately, I have encountered the batch of new stocks of Sanyo SANYO&x27;s later power amplifier module STK4196MK10. This model is actually the last improved version of the STK419X series. The external package size is the same as STK4191X, and it can be directly exchanged. The design output power is 50W + 50W @ 8 ohm, and the distortion is THD 0.01%, which is also the same level as STK4191X. Promoting general bookshelves or floor speakers can achieve satisfactory results. This thick film chip was only supplied to manufacturers who made complete machines, so it is relatively difficult to see on the market. As a comparison of the LM3886 power amplifier chip, the 68W power in its PDF file is obtained under a load of 4 ohms. The power at an 8Ω load is only 38W, which is much lower than the 50W of STK4196MK10, and the distortion degree of 0.03 is three times that of STK4196.

This machine is designed according to standard products with high and low bass adjustment and optional with and without Bluetooth version of the whole machine, the whole machine shell is made of CNC all aluminum alloy, and the central radiator isolates the power supply protection and amplification part, Ensure as little interference as possible. The power supply of this machine is divided into three groups, which respectively supply power to the power amplifier, pre-stage and protection part. The radiator of the machine is designed independently, connecting the bottom plate and the cover plate at the same time, increasing the effective heat dissipation area, making the appearance of the whole machine exquisite and compact. This machine is equipped with a high and low bass adjustment circuit for easy use.
