Analog Devices Inc. AD797ARZ-REEL Ultra Low Noise Precision Operational Amplifier

The AD797ARZ-REEL from Analog Devices Inc. is a state-of-the-art monolithic operational amplifier that sets new standards for noise performance in high-speed signal processing. This ultra-low noise, high precision op-amp is perfect for professional audio equipment, hydrophones, and sensitive instrumentation where a low noise floor is crucial for signal integrity.

With its superior sound quality and very low distortion, the AD797ARZ-REEL is also an excellent choice for audiophile-grade preamplifiers and high-end studio equipment. Its wide bandwidth of 110 MHz at a gain of +1 and 20 MHz at a gain of +10 ensures that it can handle a broad range of frequencies without compromising on clarity or detail.

The device features a very low input noise voltage of 0.9 nV/√Hz at 1 kHz, making it one of the best performers in its class. This low noise figure, combined with a very low total harmonic distortion (THD) of -120 dB, means that the AD797ARZ-REEL can reproduce audio signals with an almost perfect fidelity, preserving the nuances and dynamics of the original recording.

The operational amplifier comes in a compact R-8 package and is part of the convenient reel packaging, making it suitable for automated assembly processes. It operates over a wide supply voltage range of ±5 V to ±15 V, providing designers with flexibility in various circuit configurations. Additionally, it features a high open-loop gain of 2000 V/mV and a maximum input bias current of 2.0 μA, ensuring precise signal amplification with minimal error.

For applications requiring excellent dynamic response, the AD797ARZ-REEL has a slew rate of 20 V/μs, allowing it to handle rapid changes in input signals without lag. Its low input offset voltage of 100 μV and offset voltage drift of 0.8 μV/°C further contribute to its high precision and stability over temperature variations.

In summary, the AD797ARZ-REEL from Analog Devices Inc. is a top-tier operational amplifier that offers unparalleled noise performance and precision, making it an ideal choice for critical audio applications and high-performance instrumentation.
