Product details
Overview
ADTL082ARZ-REEL7 from Analog Devices is a dual JFET-input operational amplifier in 8-lead SOIC_N (R-8) package, delivering 5 MHz gain bandwidth, 20 V/μs slew rate, and 10 pA max input bias current at ±15 V supply. It operates across −40°C to +125°C and targets precision signal conditioning in industrial sensor interfaces and active filtering stages.
For engineers reviewing the ADTL082ARZ-REEL7 datasheet, ADTL082ARZ-REEL7 pinout, ADTL082ARZ-REEL7 application, or ADTL082ARZ-REEL7 equivalent, key selection criteria include its low-noise (16 nV/√Hz), rail-to-rail output swing capability (±13.5 V @ 10 kΩ), and A-grade temperature specification - critical for high-reliability embedded control and data acquisition systems.
Technical Context
The ADTL082ARZ-REEL7 implements a JFET-input differential pair with unity-gain stable compensation, enabling stable operation in inverting/non-inverting configurations without external compensation. Its input stage delivers high impedance (10¹² Ω) and low offset drift (10 μV/°C over −40°C to +125°C).
It features matched dual amplifiers sharing common supply pins (Pin 4: −V, Pin 8: +V), with independent inputs and outputs per channel. Channel separation exceeds 120 dB at 10 kHz, supporting multi-channel signal paths without crosstalk-induced error.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CDR | Higher max offset voltage (15 mV), higher input bias current (200 pA), commercial temp only (0°C to 70°C). | Limited to non-critical consumer or lab equipment; not qualified for extended industrial environments. | Select when cost is primary constraint and temperature range or precision is secondary. |
| OPA2134UA | Lower noise (8 nV/√Hz), lower THD (0.00008%), but higher supply current (4 mA/channel) and no A-grade temp rating. | Better for audio-grade signal chains; less suitable for battery-powered or high-temp industrial use. | Select for ultra-low-distortion audio or medical sensing where power and temperature are not limiting. |
Compared with TL082CDR, ADTL082ARZ-REEL7 offers tighter offset, lower bias current, and extended temperature support - directly improving long-term stability in unregulated enclosures. Versus OPA2134UA, it trades some noise performance for lower power and guaranteed −40°C to +125°C operation, making it more robust for factory-floor deployment.

FAQ
What is the operating temperature range for ADTL082ARZ-REEL7?
The ADTL082ARZ-REEL7 is rated for −40°C to +125°C, meeting extended industrial requirements. This specification is validated per the A-grade qualification in the ADTL082/ADTL084 Rev. B datasheet, with offset voltage drift limited to 10 μV/°C across this full range. The part is designed for use in harsh environments such as motor drives, PLC I/O modules, and under-hood automotive sensors where thermal stability is critical. ADTL082ARZ-REEL7 maintains all key parameters-including CMRR ≥80 dB and slew rate ≥20 V/μs-within this temperature window.
Is ADTL082ARZ-REEL7 pin-compatible with the TL082?
Yes, ADTL082ARZ-REEL7 uses the same 8-lead SOIC_N (R-8) pinout as the TL082, with identical terminal assignments: Pin 1 (OUT A), Pin 2 (–IN A), Pin 3 (+IN A), Pin 4 (–V), Pin 5 (+IN B), Pin 6 (–IN B), Pin 7 (OUT B), Pin 8 (+V). No PCB layout changes are required for drop-in replacement. ADTL082ARZ-REEL7 also matches TL082's electrical interface, including supply voltage range (±15 V), input common-mode range (−11 V to +15 V), and output swing behavior. ADTL082ARZ-REEL7 retains full functional compatibility while improving offset, noise, and temperature performance.
What is the maximum output voltage swing for ADTL082ARZ-REEL7 at ±15 V supply?
At ±15 V supply and 25°C, ADTL082ARZ-REEL7 delivers ±13.5 V peak output swing into a 10 kΩ load, per Table 1 of the Rev. B datasheet. Under heavier loading (2 kΩ), the swing reduces to ±12.5 V. This rail-to-rail output capability ensures minimal headroom loss when driving precision ADCs or downstream comparators. The ADTL082ARZ-REEL7 maintains ≥±12 V swing even at −40°C and +125°C, supporting consistent dynamic range across its full operating temperature range.
Does ADTL082ARZ-REEL7 support single-supply operation?
Yes, ADTL082ARZ-REEL7 supports single-supply operation up to +36 V, as confirmed by its Absolute Maximum Ratings table (Table 2). When operated from +36 V and ground, the input common-mode range extends from −0.3 V to +35.7 V, and the output can swing within 1.5 V of each rail. For example, with +30 V supply, ADTL082ARZ-REEL7 achieves ~±13.5 V output swing referenced to mid-rail. This flexibility enables use in battery-powered industrial monitors and isolated power supply feedback circuits without dual-rail generation.
What packaging and compliance information applies to ADTL082ARZ-REEL7?
ADTL082ARZ-REEL7 is supplied in an 8-lead SOIC_N (R-8) package compliant with JEDEC MS-012-AA, RoHS-compliant (Z suffix), and tape-and-reel packaged (REEL7 = 7-inch reel). The device meets Pb-free soldering profiles per J-STD-020, with a maximum lead temperature of 300°C for 60 seconds. Its thermal resistance is θJA = 158°C/W, and it is rated for storage from −65°C to +150°C. ADTL082ARZ-REEL7 is manufactured and tested to A-grade specifications, ensuring reliability in extended-temperature industrial deployments.
