The OPA2891DR is an ultra-low voltage noise, high-speed voltage feedback amplifier, which is highly suitable for applications requiring low voltage noise (including communication and imaging). This amplifier offers outstanding AC performance with a bandwidth of 180MHz, a gain (G) of 2V/V, a slew rate of 105V/µs, and a stabilization time of 70ns (0.1%). In addition, the OPA2891DR operational amplifier has a total harmonic distortion (THD) of -100 DBC at f = 1MHz and features an ultra-low noise of 0.95nV/√Hz. It is specifically designed for applications requiring low distortion and low noise, such as buffered analog-to-digital converters.


Target application

The OPA2891DR is suitable for application scenarios that require low noise and high speed, such as

Communication ‌ : For signal amplification and filtering.

Imaging ‌ : Excels in image processing and video signal amplification.

Industrial applications ‌ : As a low-noise wideband amplifier, suitable for a wide range of industrial control systems and instrumentation.

FAQ

  • 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.
