Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The SI8931D-AS4 galvanically isolated analogue amplifier has a 2.5 V input range optimised for isolated voltage detection applications. The output is a differential analogue signal proportional to the input voltage or a single-ended signal. Excellent linearity, low offset and low gain drift maintain accuracy over the full operating temperature range. Extremely high common-mode transient immunity ensures that the Si8931/32 provides accurate measurements even when high power switching occurs in motor drive systems and inverters.

● Isolated switch mode and UPS power supplies

● General industrial data acquisition and sensor interfaces

● Automotive on-board chargers, battery management systems and charging stations

• 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?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
