Product details
Overview
AD8599TRZ-EP-R7 from Analog Devices is a dual, ultralow noise (1.15 nV/√Hz at 1 kHz), ultralow distortion (−120 dB THD+N at 1 kHz) operational amplifier in an 8-lead SOIC package, specified for −55°C to +125°C operation, and used as a precision preamplifier in medical instrumentation, high-resolution data converter buffering, and professional audio signal chains.
For engineers reviewing the AD8599TRZ-EP-R7 datasheet, AD8599TRZ-EP-R7 pinout, AD8599TRZ-EP-R7 application, or AD8599TRZ-EP-R7 equivalent, key selection criteria include its 15 V/μs slew rate, 10 MHz gain bandwidth product, 120 dB minimum CMRR, ±15 V dual-supply support, and enhanced product qualification for defense/aerospace use.
Technical Context
The AD8599TRZ-EP-R7 implements a precision bipolar input stage optimized for low voltage noise and harmonic distortion across audio and DC-coupled measurement bandwidths. Its unity-gain stability, 76 nV p-p 0.1 Hz–10 Hz noise, and 2 μs settling time to 0.01% support high-fidelity signal conditioning without external compensation.
Designed for extended temperature operation, it maintains 10 μV typical offset voltage and 0.8 μV/°C drift over −55°C to +125°C, with controlled manufacturing baseline, single fabrication/assembly site, and AQEC-compliant qualification - enabling use in mission-critical analog front-ends where parametric consistency and long-term reliability are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage noise density | 1.15 nV/√Hz at 1 kHz - enables detection of sub-microvolt signals in low-level sensor interfaces |
| THD + N | −120 dB at 1 kHz - preserves dynamic range in 24-bit audio and precision ADC/DAC buffer stages |
| Slew rate | 15 V/μs at ±15 V - supports fast transient response in pulse amplification and active filter designs |
| Gain bandwidth | 10 MHz - allows stable closed-loop gain ≥10 at 1 MHz for wideband instrumentation amplifiers |
| CMRR | 120 dB min - rejects common-mode interference in differential sensor readouts and bridge circuits |
| Supply current | 5.0 mA per amplifier at ±15 V - balances performance and power in thermally constrained embedded systems |
| Offset voltage | 10 μV typical at 25°C - reduces DC error in precision integrators and low-frequency measurement paths |
Pinout & Package
AD8599TRZ-EP-R7 is housed in an 8-lead SOIC_N (R-8) package with exposed pad not present; JEDEC MS-012-AA compliant, 1.27 mm pitch, 5.00 mm × 4.00 mm body size, and 120°C/W junction-to-ambient thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Amplifier A output | Drives loads ≥600 Ω with ±13.1 V swing; requires local decoupling for stability |
| 2: –IN A | Inverting input A | High-impedance node; sensitive to PCB leakage and EMI; guard ring recommended |
| 3: +IN A | Non-inverting input A | Matches –IN A bias current; used for reference biasing or sensor excitation return |
| 4: –V | Negative supply rail | Connects to −15 V; must be decoupled within 1 cm of pin with 100 nF ceramic + 10 μF tantalum |
| 5: +IN B | Non-inverting input B | Independent of Channel A; enables dual-channel differential or gain-split configurations |
| 6: –IN B | Inverting input B | Electrically isolated from Channel A; supports independent feedback networks |
| 7: OUT B | Amplifier B output | Identical specs to OUT A; channel separation >120 dB at 10 kHz minimizes crosstalk |
| 8: +V | Positive supply rail | Connects to +15 V; shares decoupling network with –V but uses separate traces |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211AIDR | Lower noise (1.1 nV/√Hz), higher quiescent current (3.6 mA per amp), no extended temp rating | Commercial industrial use only; not qualified for −55°C to +125°C operation | Select when lower power and standard temp range suffice; avoid for aerospace/defense deployments |
| ADA4898-2ARMZ | Higher slew rate (27 V/μs), wider GBW (65 MHz), higher noise (2.9 nV/√Hz), same SOIC-8 package | Better for wideband active filters and high-speed photodiode transimpedance, less optimal for DC-coupled precision | Choose for bandwidth-critical applications where noise floor is secondary to speed |
Compared with OPA211AIDR and ADA4898-2ARMZ, AD8599TRZ-EP-R7 uniquely combines ultralow noise, −120 dB distortion, and AQEC-qualified extended temperature operation in a single SOIC-8 device - making it irreplaceable for high-reliability, low-distortion analog signal chains requiring guaranteed performance across military-grade thermal profiles.

FAQ
What is the operating temperature range of the AD8599TRZ-EP-R7?
The AD8599TRZ-EP-R7 is rated for continuous operation from −55°C to +125°C, meeting AQEC standards for defense and aerospace applications. This extended range is validated across all key parameters including offset voltage, drift, noise, and THD+N - unlike commercial variants that typically specify only −40°C to +85°C.
Does AD8599TRZ-EP-R7 support single-supply operation?
No, AD8599TRZ-EP-R7 is specified exclusively for dual-supply operation at ±15 V (with absolute maximum ratings up to ±18 V). Its input voltage range is −12.5 V to +12.5 V, and output swing is asymmetric around ground - it lacks rail-to-rail input or output capability and is not characterized for single-supply use.
What is the pin compatibility status between AD8599TRZ-EP-R7 and AD8599TRZ-EP?
AD8599TRZ-EP-R7 and AD8599TRZ-EP share identical pinout, package (SOIC_N R-8), electrical specifications, and temperature rating. The "-R7" suffix denotes 7-inch tape-and-reel packaging; both are functionally and mechanically interchangeable in PCB layout and schematic design.
How does the AD8599TRZ-EP-R7 achieve −120 dB THD+N performance?
The AD8599TRZ-EP-R7 achieves −120 dB THD+N through a proprietary bipolar input stage with matched transistor pairs, low-impedance internal nodes, and optimized biasing that minimizes crossover distortion and harmonic generation - verified at 1 kHz with 3 V RMS output into ≥1 kΩ load per the official datasheet test conditions.
Is the AD8599TRZ-EP-R7 RoHS compliant?
Yes, AD8599TRZ-EP-R7 is RoHS compliant, as indicated by the "Z" suffix in its part number per Analog Devices' ordering guide. It meets EU Directive 2011/65/EU requirements, including lead-free terminations and exemption-compliant materials, with full compliance documentation available upon request.
