  Participating awards  Best domestic IP product of 2021  The most innovative IC design company in 2021  The most influential IC design company in 2021  Company Introduction  Shenzhen Ying Ruixin Electronic Technology Co., Ltd. (IDCHIP for short) is a high-tech enterprise specializing in the design of integrated circuit chips and the design, development, production and sales of semiconductor microelectronics related products. The company was founded in 1999 and is headquartered at 1308, Building A (Tower), Union Square, North Caitian Road East Interchange, Binhe Road, Futian District, Shenzhen. IDCHIP adheres to the "people-oriented" talent strategy, and strives to attract and cultivate outstanding talents suitable for enterprise development. A group of elites from Silicon Valley and domestic experts and scholars who have been engaged in integrated circuit design for many years have been recruited. There are nearly 100 employees, more than 80% of whom have bachelor degree or above, and a R&D center of more than 20 people has been established. The staff are mainly masters, doctors and above or with intermediate technical titles, which is currently the most competitive in China's integrated circuit industry. Technical power. Mainly in accordance with the needs of the Chinese mainland, Hong Kong, Taiwan and other markets, combined with the Russian technical engineering team and the abundant logistics support in China, we provide customers with chip development and design to production, packaging, testing, sales, and after-sales technical support. The full range of high-quality, timely professional services.  Since its establishment, IDCHIP has bravely undertaken the important task of revitalizing the national integrated circuit industry, always adhere to the development path of independent innovation, and implement the development strategy of leading technology and quality. At present, it has a number of invention patents and a number of layout copyright design registrations. In the past 4 years, it has successfully transferred Trench ßpolar, HVBCD, BCD, Trench MOSFET, IGBT, FRD and other advanced processes to domestic wafer fabs, and designed and A series of high-quality LED drivers, audio power amplifiers and LED lighting chips have been developed.  IDCHIP has persistently focused on technology improvement, team building, management improvement, market development, and operation mode innovation. Thanks to the rapid development of China's electronic information industry, IDCHIP has achieved initial success in the domestic integrated circuit chip design industry. !  product description3W功放机IC芯片,AD8002

  AD8002 is a class AB, mono with shutdown mode, bridge audio power amplifier. When inputting 1KHz, 5V working voltage, the maximum driving power is: 3W, (4Ω load, THD<10%), 2W, (4Ω load, THD<1%); the total harmonic distortion noise in the audio range is less than 1% ( 20Hz·20KHz); The application circuit is simple, and only a few peripheral components are needed to provide high-quality output power. 8002A output does not require external coupling capacitors or lifting capacitors, buffer networks, and feedback resistors.  AD8002 sampling SOP package, especially suitable for low power consumption, small size portable system. It can be controlled to enter the sleep mode to reduce power consumption: 8002A has an internal overheating automatic shutdown protection mechanism. The work is stable, and the unity gain is stable. The voltage gain of the amplifier can be adjusted by configuring peripheral resistors, which is convenient for application. It is a typical chip that is well received by the market and highly recognized by users.  Basic chip application:  1.personal computer;  2. Portable consumer electronic products;  3. Passive speakers;  4. Toys and game consoles.  Reasons for voting for Ying Ruixin:  Ying Ruixin has international production standards, high-precision professional production equipment, high-efficiency, high-output production efficiency, and high-quality and comprehensive chip manufacturing capabilities.
