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.

• 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?
