Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADA4807-2ARMZ is a dual-channel, low-power, low-noise, rail-to-rail (RRIO) voltage-feedback operational amplifier packaged in an 8-MSOP (3×3mm) package, specifically designed for applications such as high-speed signal processing, precision instrumentation, and communication systems. The chip features a 180MHz bandwidth, 225V/µs slew rate, and low noise (3.1nV/√Hz), making it suitable for applications such as data acquisition, audio processing, and industrial control.

ADA4807-2ARMZ Core Features

High-Speed Performance

Bandwidth of 180MHz (-3dB), ideal for high-frequency signal processing.

Slew rate of 225V/µs ensures fast transient response.

0.1% settling time of 47ns (4V step), optimised for high-speed ADC driving.

Low Noise & Low Distortion

Input noise voltage density of 3.1nV/√Hz @100kHz, suitable for precision measurements.

THD+N (Total Harmonic Distortion + Noise) is extremely low, only 0.0002% at 1kHz, suitable for high-fidelity audio.  

Rail-to-Rail Input/Output (RRIO)  

Input can exceed the supply rail by ±50mV, and output swing approaches the power rail, enhancing dynamic range.  

Low Power Consumption & Wide Power Supply Range

Quiescent current is only 1mA (±5V supply), suitable for battery-powered devices.  

Power supply range: 2.7V to 11V (single supply) or ±1.35V to ±5.5V (dual supply), suitable for various system designs.  

Industrial-grade reliability  

Operating temperature: -40°C to +125°C, suitable for harsh environments.

• 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.
