Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AD8657ARMZ are dual-channel, micropower, precision rail-to-rail input/output amplifiers optimised for low-power and wide operating supply voltage range applications.

The AD8657ARMZ is supplied from a 2.7 V to 18 V supply and has a typical quiescent supply current of 18 μA. These devices feature ADI's patented DigiTrim® tuning technology, which results in very low out-of-phase voltages, and the AD8657ARMZ also offers high immunity to electromagnetic interference.

With low supply current, low offset voltage, very low input bias current, wide supply voltage range, and rail-to-rail inputs and outputs, the AD8657ARMZ is ideal for current monitoring in process and motor control applications. In wireless/remote sensor/transmitters, the combination of precision features of these devices is well suited for DC gain and buffering processing of sensor front ends or high impedance input sources.

The AD8657ARMZ is rated over the extended industrial temperature range (-40°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.
