Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AD8139ARDZ is an ultra-low-noise, high-performance differential amplifier with rail-to-rail output. It features low noise, high SFDR, and wide bandwidth, making it an ideal choice for driving ADCs with up to 18-bit resolution. The AD8139ARDZ is easy to use, with an internal common-mode feedback architecture that allows the output common-mode voltage to be controlled by applying a voltage to a single pin. The internal feedback loop also provides excellent output balance and suppresses even-order harmonic distortion products. Using the AD8139ARDZ, it is easy to achieve fully differential and single-ended-to-differential gain configurations. A simple external feedback network consisting of four resistors determines the amplifier's closed-loop gain.

The AD8139ARDZ is manufactured using ADI's proprietary second-generation XFCB process, enabling low distortion characteristics with input voltage noise as low as 2.25 nV/√Hz.

The AD8139ARDZ is available in an 8-pin SOIC package with an exposed pad (EP) on the bottom, rated for operation over a temperature range of -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.
