Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The OPA349NAs are ultra-low power operational amplifiers that provide 70kHz bandwidth with a quiescent current of only 1µA. These rail-to-rail input and output amplifiers are designed for battery powered applications. The input common-mode voltage range extends 200mV beyond the supply rails and the output fluctuates within 350mV rail-to-rail, maintaining a wide dynamic range. Unlike some micropower op amps, these devices are unit gain stable and require no external compensation to achieve a wide bandwidth.The OPA349NA has a low input bias current, allowing the use of large source and feedback resistors.

The OPA349NA can be used from a 1.8V to 5.5V supply with little change in performance, ensuring consistently excellent performance even when the battery is low.

• 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.
