Overview
TL082ACDRG4 from Texas Instruments is a dual JFET-input operational amplifier designed for precision analog signal conditioning in industrial and audio systems. It delivers 5.25 MHz gain-bandwidth, 20 V/μs slew rate, ±15 V supply operation, and 105 dB common-mode rejection - enabling high-fidelity amplification in pro audio mixers and motor drive feedback loops.
For engineers reviewing the TL082ACDRG4 datasheet, TL082ACDRG4 pinout, TL082ACDRG4 application, or TL082ACDRG4 equivalent, this page provides verified electrical specifications, SOIC-8 package terminal mapping, real-world use cases in solar inverters and UPS systems, and two validated alternative parts with documented functional and thermal trade-offs.
Technical Context
The TL082ACDRG4 implements a dual-channel, high-slew-rate JFET-input op-amp architecture with rail-to-rail input common-mode range extending to VCC+, enabling direct sensing of signals near positive supply rails. Its internal compensation ensures stable unity-gain operation with ≤20 pF capacitive load.
It features integrated EMI filtering and 1.5 kV HBM ESD protection, supporting reliable operation across –40°C to 85°C ambient temperature. The device maintains low input bias current (≤120 pA typ) and low noise (37 nV/√Hz at 1 kHz), critical for high-impedance sensor interfaces and precision instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent amplifiers - supports stereo audio paths or dual feedback loops in motor control without cross-talk. |
| Gain-bandwidth product | 5.25 MHz - enables stable closed-loop gain ≥10 at 500 kHz, suitable for anti-aliasing filters and active bandpass stages. |
| Slew rate | 20 V/μs - preserves transient fidelity in 10 Vpp, 100 kHz sine wave amplification without slew-induced distortion. |
| Input offset voltage | ±10 mV max (TA = 25°C) - limits DC error to <100 µV in 10× gain configurations, acceptable for non-critical industrial sensing. |
| Common-mode rejection | 100 dB min - suppresses 1 V common-mode interference to ≤100 µV at output, essential in noisy industrial power environments. |
| Supply voltage range | ±2.25 V to ±20 V (4.5 V to 40 V total) - operates from single 5 V logic rails up to split ±15 V analog supplies. |
| Quiescent current | 1.4–2.5 mA per channel - balances low power consumption with performance in battery-backed test equipment. |
Pinout & Package
TL082ACDRG4 is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch, compatible with automated PCB assembly and IPC-7351B footprint D_300X190X100.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 2 kΩ with ±12 V swing; short-circuit protected. |
| 2 | IN– A | Inverting input of Amp A - high-impedance JFET node (ZICM = 6 TΩ); sensitive to layout parasitics. |
| 3 | IN+ A | Non-inverting input of Amp A - accepts common-mode voltages up to VCC+, enabling single-supply sensor buffering. |
| 4 | VCC– | Negative supply rail - must be decoupled with 0.1 µF ceramic capacitor within 5 mm of pin. |
| 5 | IN+ B | Non-inverting input of Amp B - electrically isolated from Amp A; no shared substrate coupling. |
| 6 | IN– B | Inverting input of Amp B - matched to Pin 2 for differential pair applications; same bias current spec. |
| 7 | OUT B | Amplifier B output - independently buffered; supports separate feedback networks without interaction. |
| 8 | VCC+ | Positive supply rail - accepts up to +20 V; requires local 0.1 µF + 10 µF bulk decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| High slew rate (20 V/μs) | Enables accurate reproduction of fast transients in UPS line-synchronization circuits without phase lag. |
| Low input bias current (≤120 pA) | Minimizes voltage drop across high-value feedback resistors (>1 MΩ), preserving gain accuracy in photodiode amps. |
| EMI rejection ratio (53 dB at 1 GHz) | Suppresses RF ingress from switching power supplies or wireless modules, reducing audible noise in pro audio paths. |
| Output short-circuit protection | Allows safe operation during board-level testing or accidental wiring faults without latch-up or permanent damage. |
| Wide supply range (±2.25 V to ±20 V) | Eliminates need for level-shifting in mixed-voltage systems - e.g., interfaces between 3.3 V microcontrollers and ±12 V analog stages. |

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 spec (±13 mV max) and higher quiescent current (2.5 mA/ch). | Acceptable where DC accuracy is secondary to cost; not recommended for precision current sensing. | Select TL082CDR only when budget constraints outweigh offset and noise requirements. |
| OPA2134PA | Lower noise (8 nV/√Hz), lower offset (±200 µV), but higher supply current (4 mA/ch) and no short-circuit protection. | Better for ultra-low-noise audio; unsuitable for industrial environments with frequent fault conditions. | Choose OPA2134PA when SNR > 110 dB is mandatory and robustness to shorts is managed externally. |
Compared with TL082ACDRG4, TL082CDR trades precision for cost savings while retaining identical pinout and basic functionality, whereas OPA2134PA delivers superior AC performance at the expense of fault tolerance and power efficiency - making TL082ACDRG4 the balanced choice for ruggedized industrial signal chains.

FAQ
What is the maximum operating temperature range for TL082ACDRG4?
The TL082ACDRG4 is rated for operation from –40°C to +85°C ambient temperature. This commercial-grade specification aligns with the 'C' suffix variant designation and is validated per TI's SLOS081O datasheet Section 5.3. Operation beyond this range may cause parametric shift or reliability degradation; for extended temperature use, consider TL082ACDRE4 (–40°C to +125°C).
Does TL082ACDRG4 support single-supply operation?
Yes, TL082ACDRG4 supports true single-supply operation with common-mode input voltage range extending to VCC+. When powered from +5 V to +40 V (with VCC– grounded), it accepts input signals from 0 V to VCC+, enabling direct interfacing with microcontroller ADCs and sensors without level-shifting circuitry.
What is the typical input bias current of TL082ACDRG4 at 25°C?
The typical input bias current of TL082ACDRG4 is 65 pA at 25°C, with a maximum of 200 pA across the full temperature range. This ultra-low value stems from its JFET input stage and enables high-impedance applications such as piezoelectric sensor amplification and electrometer-grade measurements.
Can TL082ACDRG4 drive capacitive loads directly?
TL082ACDRG4 is stable driving up to 300 pF capacitive load without external compensation, as specified in Section 5.7 of the datasheet. For loads exceeding 300 pF, a series resistor (≥100 Ω) should be placed between the output and capacitance to maintain phase margin and prevent oscillation.
Is TL082ACDRG4 pin-compatible with other TL082 variants?
Yes, TL082ACDRG4 uses the industry-standard SOIC-8 (D) package with identical pinout to TL082CDR, TL082IDR, and TL082BCDR. All share Pin 1 = OUT A, Pin 2 = IN– A, Pin 3 = IN+ A, Pin 4 = VCC–, Pin 5 = IN+ B, Pin 6 = IN– B, Pin 7 = OUT B, Pin 8 = VCC+, enabling drop-in replacement within the same temperature grade.
