AD8597ACPZ-REEL

Overview

The AD8597ACPZ-REEL is a single-channel, ultralow noise and distortion operational amplifier manufactured by Analog Devices. It features a voltage noise density of 1.07 nV/√Hz at 1 kHz and total harmonic distortion of −120 dB at 1 kHz. The device offers a gain bandwidth product of 10 MHz and a slew rate of 14 V/μs. Input offset voltage is typically 10 μV with a drift of 0.8 μV/°C. Operating from ±5 V to ±18 V supplies, it draws approximately 4.8 mA per amplifier. Common-mode rejection ratio reaches 135 dB, and power supply rejection ratio is 140 dB. It is housed in an 8-lead LFCSP package.

Feature Summary

• Ultralow voltage noise density of 1.1 nV/√Hz for high-fidelity signal processing
• Harmonic distortion as low as −120 dB ensuring wide dynamic range
• Fast transient response with 14 V/μs slew rate and 10 MHz bandwidth
• High precision with 10 μV typical input offset voltage

Applications

• Professional audio preamplifiers
• Medical and physiological measurements
• Precision data conversion buffering
• Imaging systems
• ATE and precision testers

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the AD8597 series includes both SOIC and LFCSP options. Confirm that the REEL designation aligns with automated surface-mount assembly requirements. Ensure the temperature grade corresponds to the intended operating environment specifications defined in the datasheet.

Selection Notes

Select this component when source impedances are kept below 1 kΩ to maximize low-noise performance. Consider the 10 MHz bandwidth and 14 V/μs slew rate for applications requiring fast settling times. Evaluate the ±5 V to ±18 V supply range against system power constraints. Verify that the 8-lead LFCSP package fits the available PCB footprint and thermal management strategy.

Part Context

This part belongs to the AD8597/AD8599 family of ultralow noise operational amplifiers designed for demanding analog signal paths. It serves as the single-channel counterpart to the dual-channel AD8599. The series is engineered to provide superior audio and instrumentation performance through specialized input transistor architectures that minimize both voltage and current noise contributions.
