AD8021ARZ-REEL7 SOIC-8 RF Low Noise Amplifier ADI Original Stock

describe

AD8021 is an exceptionally high performance, high-speed voltage feedback amplifier that can be used in 16 bit resolution systems. It is designed to have low voltage and low current noise (typical 2.1nV/√ Hz) and 2.1pA/√ Hz typical), while operating at the lowest static power supply current (7 mA @ ± 5 V) in today's high-speed, low noise operational amperes. The AD8021 operates on a wide range of power supply voltages from ± 2.25 V to ± 12 V, as well as a single 5V power supply, making it an ideal choice for high-speed and low-power instruments. An output disable pin allows for further reduction of the static power supply current to 1.3 mA.

AD8021 allows users to choose the gain bandwidth product that is most suitable for the application. By using a capacitor, users can compensate for the gain required for AD8021 with minimal bandwidth trade-offs. AD8021 is a high-performance amplifier that stabilizes to 0.01% within 23 ns. It has a fast overload recovery of 50 ns.

AD8021 is super temperature stable, with low input bias voltage drift and input bias current drift, respectively 0.5 μ V/° C and 10nA/° C. AD8021 can also drive a 75 Ω line with a ± 3 V video signal.

AD8021 is technologically superior and much cheaper than similar devices with higher quiescent current. AD8021 is a high-speed, general-purpose amplifier that is very suitable for various gain configurations and can be used throughout the entire signal processing chain and control loop. AD8021 comes in standard 8-lead SOIC and MSOP packaging, with an industrial temperature range of -40 ° C to+85 ° C.
