Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX6078AMWT25 high-precision voltage reference family features low drift and low noise, with a maximum supply current of just 15μA. Low-frequency noise is less than 12μVsub>PP (2.5V output voltage option), and the temperature coefficient of the output voltage is less than 10ppm/°C.

The reference output can sink or source up to 3mA of load current, with an initial accuracy of 0.04% at the highest grade. The low drift and low noise specifications enhance system accuracy, making it an ideal choice for high-precision industrial applications. The noise suppression (NR) input pin allows connection of an external capacitor to reduce broadband noise. The available output voltages include 1.25V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V.

The MAX6078AMWT25 is housed in a small, 6-ball WLP package, making it ideal for systems with limited board space. It operates on an input voltage range of 2.3V to 5.5V and functions within an extended temperature range of -55°C to +125°C.

• 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.
