AD8599TRZ-EP-R7

Overview

The AD8599TRZ-EP-R7 is a dual, ultralow distortion, and ultralow noise operational amplifier from Analog Devices. It features a voltage noise density of 1.15 nV/√Hz at 1 kHz and total harmonic distortion plus noise of −120 dB at 1 kHz. The device offers a gain bandwidth product of 10 MHz and a slew rate of 15 V/μs to 16 V/μs depending on configuration. It operates with a supply current of 5.0 mA per amplifier and maintains an input offset voltage of 10 μV typical. The component supports dual-supply operation up to ±18 V and functions within a temperature range of −55°C to +125°C.

Feature Summary

• Ultralow noise density of 1.15 nV/√Hz for high-fidelity signal processing
• Ultra-low distortion performance with −120 dB THD+N at audio frequencies
• Enhanced product reliability with controlled manufacturing baseline and single assembly site
• Extended industrial temperature range suitable for harsh environments

Applications

• Professional audio preamplifiers
• ATE and precision testers
• Imaging systems
• Medical and physiological measurements
• Precision detectors and instruments

Procurement Notes

Verify the specific ordering suffix R7 corresponds to tape and reel packaging requirements. Confirm that the EP designation indicates Enhanced Product status, which implies controlled manufacturing baselines and extended temperature ranges suitable for defense or aerospace applications. Ensure compatibility with dual-supply configurations up to ±18 V and validate thermal management for the 8-lead SOIC package under maximum operating conditions.

Selection Notes

Select this component when ultralow noise and distortion are critical for signal integrity in audio or medical instrumentation. The dual-channel architecture simplifies designs requiring multiple amplification stages. Consider the 10 MHz gain bandwidth and fast settling time for buffering high-resolution data converters. Verify that the ±15 V typical supply requirement aligns with system power constraints and that the 8-lead SOIC package fits the available PCB footprint.

Part Context

This part belongs to the AD8599-EP family of enhanced products designed for demanding applications. It shares core electrical characteristics with the standard AD8599 but includes rigorous quality controls such as one fabrication site and one assembly site. The EP variant ensures consistent performance over the extended temperature range and provides qualification data availability upon request for regulated industries.

Replacement Considerations

The AD8599TRZ is a non-enhanced equivalent with similar electrical specifications but lacks the controlled manufacturing baseline and extended temperature qualification of the EP version. Substitution requires verifying that the standard product's temperature range and reliability standards meet the application requirements.
