Product details
Overview
AD8599TRZ-EP from Analog Devices is a dual, ultralow-noise, ultralow-distortion operational amplifier optimized for precision preamplification in high-fidelity and measurement-critical systems. It delivers 1.15 nV/√Hz voltage noise density at 1 kHz, −120 dB THD+N at 1 kHz, and 15 V/μs slew rate under ±15 V supplies, enabling use in professional audio preamps, medical physiological signal conditioning, and high-resolution data converter buffering.
For engineers reviewing the AD8599TRZ-EP datasheet, AD8599TRZ-EP pinout, AD8599TRZ-EP application, or AD8599TRZ-EP equivalent, key selection criteria include its extended temperature range (−55°C to +125°C), enhanced product qualification for defense/aerospace, 10 MHz gain bandwidth, and guaranteed CMRR ≥120 dB across full operating temperature.
Technical Context
The AD8599TRZ-EP employs a precision bipolar input stage delivering ultralow voltage noise and distortion while maintaining unity-gain stability. Its architecture supports dual-supply operation up to ±15 V with rail-to-rail output swing capability (±13.4 V into 2 kΩ) and low input offset voltage drift (0.8 µV/°C typical).
Designed for demanding analog signal chains, it features correlated/uncorrelated current noise ≤5.3 pA/√Hz, 76 nV p-p 0.1 Hz–10 Hz noise, and channel separation of −120 dB at 10 kHz-enabling simultaneous high-fidelity amplification of two independent low-level signals without crosstalk degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Noise Density | 1.15 nV/√Hz at 1 kHz - enables detection of sub-µV signals in audio and sensor front-ends |
| THD + N | −120 dB at 1 kHz, G = 1 - preserves harmonic integrity in precision instrumentation and medical amplifiers |
| Gain Bandwidth Product | 10 MHz - supports stable closed-loop gain ≥10 at 1 MHz for anti-aliasing and reconstruction filters |
| Slew Rate | 15 V/μs at ±15 V - ensures <2 µs settling to 0.01% for 10 V step, critical for fast data acquisition buffering |
| CMRR | 120 dB min (−12.5 V to +12.5 V common-mode) - rejects power supply and EMI-induced common-mode interference |
| Supply Current per Amp | 5.0 mA typical at ±15 V - balances low-noise performance with thermal management in dual-channel designs |
| Operating Temp Range | −55°C to +125°C - qualified for extended-environment aerospace, downhole, and military electronics |
Pinout & Package
The AD8599TRZ-EP is housed in an 8-lead SOIC_N (narrow-body) package (JEDEC MS-012-AA, package option R-8) with exposed paddle not present; thermal resistance θJA = 120°C/W on 4-layer JEDEC PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT A | Amplifier A output | Drives external load or next-stage input; capable of ±13.4 V swing into 2 kΩ |
| 2 - –IN A | Inverting input A | High-impedance node (12.1 pF differential capacitance); requires matched trace layout for THD optimization |
| 3 - +IN A | Non-inverting input A | Low bias current (25 nA typ); referenced to system ground or common-mode voltage |
| 4 - –V | Negative supply rail | Connects to −15 V (or −4.5 V min); must be stable before applying input signals |
| 5 - +IN B | Non-inverting input B | Independent channel input; shares same CMRR and noise specs as Channel A |
| 6 - –IN B | Inverting input B | Electrically isolated from Channel A; channel separation −120 dB at 10 kHz prevents inter-channel coupling |
| 7 - OUT B | Amplifier B output | Functionally identical to OUT A; supports dual-signal processing without shared path degradation |
| 8 - +V | Positive supply rail | Connects to +15 V (or +4.5 V min); supplies both amplifiers simultaneously per power sequencing requirement |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow 0.1 Hz–10 Hz noise | 76 nV p-p - minimizes baseline wander in ECG/EEG and precision detector outputs |
| Enhanced product qualification | AQEC-compliant with controlled fab/assembly/test sites - meets MIL-PRF-38535 Class K requirements for space-grade reliability |
| High open-loop gain | 116 dB typical (≥106 dB over full temp) - ensures <1 ppm gain error in 100× closed-loop configurations |
| Low input offset drift | 0.8 µV/°C typical - maintains calibration stability across −55°C to +125°C without active compensation |
| Fast settling time | 2 µs to 0.01% for 10 V step - enables >500 kSPS sampling in buffered SAR ADC front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP275GPZ | Higher noise (3.5 nV/√Hz), lower GBW (12 MHz), no extended temp rating | Commercial-grade audio only; unsuitable for aerospace or medical certified designs | Select when cost sensitivity outweighs noise and qualification requirements |
| ADA4898-2YRDZ | Lower noise (0.9 nV/√Hz), higher supply current (10.5 mA), same −55°C to +125°C range | Better noise performance but higher power dissipation limits use in thermally constrained enclosures | Select when ultimate voltage noise dominates over quiescent power budget |

FAQ
What is the maximum supply voltage rating for the AD8599TRZ-EP?
The AD8599TRZ-EP has an absolute maximum supply voltage of ±18 V per rail, though it is specified for operation from ±4.5 V to ±15 V. Operation at ±18 V is permissible only under no-signal, non-operational stress conditions per Absolute Maximum Ratings; functional operation above ±15 V is not characterized and may compromise THD+N or noise performance.
Does the AD8599TRZ-EP require external compensation for unity-gain stability?
No, the AD8599TRZ-EP is internally compensated and unity-gain stable across its full operating temperature range (−55°C to +125°C). No external capacitors or feedback networks are needed to ensure stability in G = 1 configurations, simplifying layout and reducing component count in precision buffer designs.
How does the AD8599TRZ-EP's channel separation performance impact dual-channel applications?
The AD8599TRZ-EP provides −120 dB channel separation at 10 kHz, meaning less than 10−12 of the signal from one amplifier couples into the other. This enables true independent amplification of two low-level signals-such as stereo audio channels or differential sensor pairs-without measurable crosstalk-induced distortion or gain error.
Is the AD8599TRZ-EP RoHS compliant and lead-free?
Yes, the "Z" suffix in AD8599TRZ-EP indicates RoHS-compliant packaging with lead-free terminations. The device meets EU RoHS Directive 2011/65/EU and is compatible with standard Pb-free reflow profiles, including peak temperatures up to 260°C for 10 seconds.
What thermal considerations apply when using the AD8599TRZ-EP in high-temperature environments?
With θJA = 120°C/W on a standard 4-layer JEDEC board, the AD8599TRZ-EP dissipates 15 mW per amplifier (5.0 mA × 15 V), resulting in ~1.8°C rise above ambient at full load. At +125°C ambient, junction temperature remains well below the 150°C limit, provided PCB copper area and airflow meet minimum layout guidelines in the datasheet.
