Recently, the SX495EO automotive chip developed by China Electronics Technology Research Institute, a company in Xiyong Microelectronics Park, has successfully passed AEC-Q100 certification.http://www.ic-bom.com/

The SX495EO automotive chip can be used for driving assistance systems (ADAS), body control and lighting systems, multimedia entertainment systems, and instrument information systems.

The SX49XEO series is a low-power operational amplifier independently designed and taped by the electronics chip. Among them, the SX494EO is a four channel product and the SX495EO is a dual channel product. The electrical characteristics of each channel are consistent. This series of products can be used in single power applications. If the voltage difference between positive and negative power sources is within the specified range and is at least 1.5V higher than the input common mode voltage, dual power applications can also be used; Built in frequency compensation, achieving single gain stability; The use of micro plastic packaging provides excellent value for cost sensitive applications.

The automotive chip patching project has an urgent, forward-looking, and strategic core position and role in the industrial foundation sector. CETC chips shoulder a heavy responsibility, based on their own technological foundation, quickly establish a special team, and carry out technical research and vehicle certification work for dozens of "bottleneck" automotive chips. The team technical expert said, "Mastering key core technologies in my own hands is of utmost importance, and I am honored and excited to be a member of the team.http://www.ic-bom.com/

The AEC-Q100 certification is an important entry point for integrated circuit component manufacturers to enter international automotive manufacturers‘ modules. "The head of the Electronics Technology chip amplifier team said that this certification is a set of stress standard tests designed mainly for integrated circuit products in automotive applications, belonging to the globally recognized reliability standards for automotive integrated circuit components, aiming to comprehensively evaluate the reliability and safety of the quality of automotive components.http://www.ic-bom.com/

During the research and development process, team members deeply understood the tight schedule and heavy workload of this task. The standard for automotive grade chips is second only to military grade chips, far higher than industrial and civilian grade chips, "explained the technical expert. During the research and development process, the amplifier team actively carried out research on low-power dual channel operational amplifier technology. Through close communication with relevant automotive companies, extensive literature review, and countless modifications, the circuit design and layout design of the SX495EO were quickly completed in just two months. In the end, the evaluation of indicators and the development of samples were completed in just five months.

Faced with the reliability assessment of automotive operational amplifiers from scratch, the amplifier team simultaneously conducted research on high reliability technology for vehicle specifications, searched various channels for information, studied the standard reports related to vehicle specification certification word by word, and ultimately developed a set of vehicle specification certification test plans for operational amplifiers. And in April 2023, the third-party AEC-Q100 certification of the automotive amplifier SX495EO was completed in advance, with about a year left before the demand time, achieving the engineering production capacity of the SX495EO. At present, the chip has achieved sales, with an order volume of over 40000 units in the first year.http://www.ic-bom.com/
