Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AMC1301DWVR is an isolated precision amplifier where the output and input circuits are separated by a barrier that is highly resistant to EMI. The barrier is certified to provide enhanced isolation up to 7070 V PEAK in accordance with DIN EN IEC 60747-17 (VDE 0884-17) and UL1577, and can support operating voltages up to 1 kV RMS.

This isolation separates devices in the system that operate at different common mode voltage levels, preventing high voltage surges from causing electrical damage to the low voltage side of the device or injury to the operator.

The AMC1301DWVR's inputs are optimised for direct connection to shunt resistors or other low voltage level sources. Excellent DC accuracy and low temperature drift support precise current control for on-board chargers (OBCs), DC/DC converters, inverters, or other high-voltage applications. The AMC1301DWVR's integrated common-mode overvoltage and no high-side supply voltage detection simplifies system-level design and diagnostics.

The AMC1301DWVR operates over the extended industrial temperature range of -40°C to +125°C and is available in a wide-body 8-pin SOIC package.

• 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.
