AD8597ACPZ-R2

Overview

The AD8597ACPZ-R2 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 to 16 V/μs depending on supply conditions. It operates with a typical supply current of 4.8 mA per amplifier and supports dual supplies ranging from ±5 V to ±18 V. The input offset voltage is typically 10 μV, and the common-mode rejection ratio reaches 135 dB. It is housed in an 8-lead LFCSP package.

Feature Summary

• Ultralow voltage noise density of approximately 1.1 nV/√Hz for high-fidelity signal amplification
• Ultra-low harmonic distortion of −120 dB THD+N at audio frequencies
• High slew rate and wide bandwidth suitable for fast transient response
• Low input offset voltage and drift ensuring precision DC performance

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 R2 corresponds to the reel packaging configuration required for your assembly line. Confirm that the LFCSP-8 package variant matches your PCB footprint design. Ensure the operating temperature range of −40°C to +125°C aligns with your environmental specifications. Cross-reference the datasheet revision F electrical characteristics against your circuit simulation requirements.

Selection Notes

Select this component when source impedances are kept below 1 kΩ to leverage its ultralow voltage noise. It is optimized for applications requiring high dynamic range and low distortion rather than rail-to-rail input capabilities. Consider the thermal resistance of the LFCSP package if high power dissipation is expected. Evaluate the need for external protection resistors if input overvoltage conditions are possible.

Part Context

The AD8597 is part of Analog Devices' series of low-noise operational amplifiers, designed specifically for demanding analog signal processing tasks. 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. The family targets high-performance instrumentation and audio markets where signal integrity is critical.

Replacement Considerations

The AD8599 is the dual-channel equivalent within the same family. For single-channel replacements, consider the AD797 or ADA4004-1 based on specific noise and speed trade-offs. Verify pin compatibility and thermal performance before substituting.
