Environmental adaptability ‌ : Specifically designed for harsh working conditions, it features high electromagnetic compatibility, enhanced protection circuits and comprehensive diagnostic functions.

Calibration support ‌ : end-to-end calibration is supported, and OWI or I²C interfaces are provided to simplify the configuration process.

Output method

RAA2S4261B5HNP offers two communication interfaces:

Youdaoplaceholder0 SENT output ‌ : Achieve highly reliable data transmission through a single output pin.

I2C output ‌ : Supports digital signal transmission and is compatible with mainstream automotive communication protocols.

The RAA2S4261B5HNP device has passed the strict certification of the automotive industry and is suitable for scenarios such as pressure sensors that require high-precision signal conditioning.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
