AD8597ACPZ-REEL7

Overview

The AD8597ACPZ-REEL7 is a single-channel, ultralow noise and distortion operational amplifier manufactured by Analog Devices Inc. It features a gain bandwidth product of 10 MHz and a slew rate of 14 V/µs. The device operates on supply voltages ranging from ±5 V to ±18 V with a typical supply current of 4.8 mA per amplifier. Key electrical specifications include an input offset voltage of 10 µV, an input bias current of 200 nA, and a common-mode rejection ratio of 135 dB. Voltage noise density is 1.07 nV/√Hz at 1 kHz, with peak-to-peak noise under 76 nV in the 0.1 Hz to 10 Hz range. Total harmonic distortion is −120 dB at 1 kHz. The component is housed in an 8-lead LFCSP package and supports operation from −40°C to +125°C.

Feature Summary

• Ultralow voltage noise density of 1.1 nV/√Hz for high-fidelity signal amplification
• Low harmonic distortion of −120 dB THD at audio frequencies
• Wide dynamic range suitable for precision preamplifier applications
• Fast settling time and high slew rate for medical and instrumentation use

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 (e.g., REEL7) against the manufacturer's official documentation to confirm packaging type and quantity. Ensure the temperature grade matches the required operating environment. Confirm that the LFCSP-8 package dimensions align with the target PCB footprint. Cross-reference the datasheet revision to validate all electrical parameters before finalizing procurement.

Selection Notes

Select this component when source impedance is below 1 kΩ to minimize total input-referred noise. Consider the ±5 V to ±18 V supply range requirements. Evaluate the 10 MHz bandwidth against the application's frequency needs. Verify compatibility with the 8-lead LFCSP or SOIC packages if alternative variants are considered. Ensure low output capacitance loads to prevent overshoot issues.

Part Context

The AD8597 is part of the AD8597/AD8599 series of ultralow noise operational amplifiers designed for high-performance analog signal chains. It serves as the single-channel counterpart to the dual-channel AD8599. Both devices share similar electrical characteristics but differ in channel count and package availability. This series targets applications requiring superior dynamic range and minimal signal degradation.

Replacement Considerations

The AD8599 is the dual-channel equivalent within the same family. Other low-noise alternatives include the ADA4004-1 and AD797, though their electrical specifications and package options differ significantly.
