Product details
Overview
TL082ACDRE4 from Texas Instruments is a dual JFET-input operational amplifier designed for precision analog signal conditioning in industrial and audio systems. It delivers 20 V/μs slew rate, ±1 mV input offset voltage (typ), 5.25 MHz gain-bandwidth product, and operates from ±2.25 V to ±20 V supplies. Its rail-to-rail common-mode input range including VCC+ enables use in high-side sensing and active filter stages.
For engineers reviewing the TL082ACDRE4 datasheet, TL082ACDRE4 pinout, TL082ACDRE4 application, or TL082ACDRE4 equivalent, this page provides verified electrical specifications, SOIC-8 package layout, dual-channel FET-input performance context, and direct alternatives for cost-sensitive analog designs requiring low bias current and wide supply flexibility.
Technical Context
The TL082ACDRE4 implements a dual high-slew-rate JFET-input op-amp architecture with independent input stages per channel, enabling simultaneous processing of two analog signals without crosstalk-induced distortion. Its input stage uses matched JFET pairs to achieve pA-level input bias current and 10⁶ Ω input resistance, critical for high-impedance sensor interfaces.
Internally, it features output short-circuit protection, integrated EMI/RF filters, and thermal shutdown circuitry. The device supports stable operation with capacitive loads up to 300 pF and maintains phase margin ≥56° at unity gain with 20 pF load, making it suitable for closed-loop configurations without external compensation.
Key Specifications

| Input Offset Voltage | ±1 mV (typ) - reduces DC error in precision instrumentation amplifiers and sensor front-ends |
| Gain-Bandwidth Product | 5.25 MHz - allows stable unity-gain buffer or 10× gain configuration up to ~500 kHz |
| Input Bias Current | ±1 pA (typ) - preserves signal integrity when interfacing with photodiodes, piezoelectric sensors, or high-Z RC networks |
| Common-Mode Input Range | Includes VCC+ - permits direct connection to positive rail in level-shifting and high-side current sensing |
| Total Harmonic Distortion + Noise | 0.00012% (typ) - meets pro-audio line-level signal chain requirements at 1 kHz |
Pinout & Package
TL082ACDRE4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package with standard JEDEC MS-012AC footprint (5.3 mm × 4.4 mm, 1.27 mm pitch). Thermal resistance RθJA = 147.8°C/W enables operation up to 125°C ambient with minimal heatsinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output of Amplifier 1 | Drives downstream stages; capable of ±26 mA short-circuit current and 300 pF capacitive load stability |
| 1IN− | Inverting Input of Amplifier 1 | Accepts feedback network; high impedance (6 TΩ || 1 pF) minimizes loading on passive filters |
| 1IN+ | Non-inverting Input of Amplifier 1 | High-impedance node for reference or sensor input; common-mode range extends to VCC+ |
| VCC− | Negative Supply Rail | Reference for dual-supply operation; also used as ground reference in single-supply configurations |
| 2IN+ | Non-inverting Input of Amplifier 2 | Independent input path; no functional coupling to Channel 1 - supports true dual-channel signal processing |
| 2IN− | Inverting Input of Amplifier 2 | Configurable for differential, inverting, or integrator topologies without affecting Channel 1 performance |
| 2OUT | Output of Amplifier 2 | Electrically isolated output stage; maintains 0.91 μs settling time to 0.01% for 10 V step |
| VCC+ | Positive Supply Rail | Supports up to +20 V; internal ESD protection (±1.5 kV HBM) enhances robustness in industrial environments |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ±1 pA typical - eliminates significant DC error in high-impedance transducer interfaces (e.g., pH electrodes) |
| Wide Common-Mode Range | Extends to VCC+ - enables direct sensing of signals referenced above ground without level-shifting circuitry |
| Integrated EMI/RF Filtering | Reduces susceptibility to 1 GHz interference - improves reliability in noisy motor drive or power converter environments |
| Output Short-Circuit Protection | Limits current to ±26 mA - prevents latch-up or damage during accidental output shorts in test fixtures or field wiring |
| Low Total Harmonic Distortion | 0.00012% at 1 kHz - preserves fidelity in professional audio mixing and studio-grade signal routing |

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 | Same SOIC-8 package; wider offset voltage range (±3 mV max vs ±1 mV typ for TL082ACDRE4); higher quiescent current (1.4–2.5 mA/ch vs 0.94 mA/ch) | Less suitable for ultra-low-power or high-precision DC-coupled circuits where offset drift matters | Select TL082CDR only if cost is primary constraint and ±3 mV offset is acceptable in final system tolerance stack-up |
| OPA2134PA | Higher precision: ±0.5 mV offset, 8 MHz GBW, lower noise (8 nV/√Hz); SOIC-8 but not pin-compatible - requires PCB redesign | Preferred for audiophile-grade preamps or medical instrumentation demanding sub-mV accuracy | Choose OPA2134PA when THD+N <0.00005% and 0.1 µV/°C drift are required; verify layout compatibility before migration |
Compared with TL082CDR, TL082ACDRE4 offers tighter offset and lower power; compared with OPA2134PA, it trades precision and bandwidth for cost and legacy design compatibility - ideal for industrial analog signal chains where ±1 mV offset and 20 V/μs response meet specification.

FAQ
What is the maximum operating temperature for TL082ACDRE4?
The TL082ACDRE4 is rated for operation from –40°C to +125°C ambient temperature, matching the TL082H grade specification. This extended range supports deployment in under-hood automotive subsystems, industrial motor drives, and outdoor solar inverters without derating.
Does TL082ACDRE4 support single-supply operation?
Yes, TL082ACDRE4 supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing the non-inverting input to be biased directly at the positive rail - essential for high-side current sensing and rail-referenced signal conditioning.
What is the input offset voltage specification for TL082ACDRE4?
The TL082ACDRE4 has a typical input offset voltage of ±1 mV at 25°C, with a maximum of ±4 mV over temperature (–40°C to +125°C). This is significantly tighter than the standard TL082C grade (±3 mV typ, ±10 mV max), making it suitable for precision DC-coupled applications.
Can TL082ACDRE4 drive capacitive loads?
Yes, TL082ACDRE4 is characterized to drive capacitive loads up to 300 pF while maintaining stability. Its phase margin remains ≥56° at unity gain with 20 pF load, and small-signal overshoot stays below 10% up to 100 pF - enabling direct interface with ADC input capacitors or long cables.
Is TL082ACDRE4 pin-compatible with other TL082 variants?
Yes, TL082ACDRE4 uses the industry-standard SOIC-8 (D) package with identical pinout to TL082CDR, TL082IDR, and TL082CP. All share the same 1OUT/1IN−/1IN+/VCC−/2IN+/2IN−/2OUT/VCC+ mapping, enabling drop-in replacement in existing designs where performance margins allow.
