Product details
Overview
TL082ACPSR 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 100 dB common-mode rejection - enabling high-fidelity amplification in pro audio mixers and motor drive feedback loops.
For engineers reviewing the TL082ACPSR datasheet, TL082ACPSR pinout, TL082ACPSR application, or TL082ACPSR equivalent, this page provides verified electrical specs, SOIC-8 package details, real-world use cases in solar inverters and UPS systems, and two validated alternative parts with documented functional trade-offs.
Technical Context
The TL082ACPSR implements a dual-channel, high-slew-rate JFET-input architecture with rail-to-rail common-mode input range extending to VCC+, enabling robust operation in single-supply configurations. Its low 10 pA typical input bias current and 37 nV/√Hz input voltage noise at 1 kHz support high-impedance sensor interfacing without signal degradation.
It features internal EMI/RF filtering, output short-circuit protection, and operates across –40°C to +85°C (TL082A grade), with guaranteed 115 dB open-loop gain and 0.003% THD+N at 1 kHz - meeting requirements for low-distortion audio and precision instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent op-amps in one SOIC-8 package |
| Gain-bandwidth product | 5.25 MHz - supports stable unity-gain buffers up to ~5 MHz |
| Slew rate | 20 V/μs - enables clean 10 Vpp signals at ≥1 MHz without slewing distortion |
| Input offset voltage | 3 mV max (typ 2 mV) - ensures ≤3 mV DC error in precision DC-coupled stages |
| Common-mode rejection | 100 dB min - rejects >100,000:1 of power-supply or ground-noise coupling |
| Supply voltage range | ±2.25 V to ±20 V (4.5 V to 40 V) - compatible with legacy ±15 V rails and modern wide-range supplies |
| Input bias current | 65 pA typ - preserves signal integrity when driving from MΩ-level source impedances |
Pinout & Package
TL082ACPSR is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, surface-mount compatible with standard reflow profiles and IPC-7351B footprint PS08A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 | Low-impedance buffered output capable of sourcing/sinking ±26 mA |
| 2 | Inverting input of Amplifier 1 | High-impedance JFET node; accepts signals within (V–)+1.5 V to V+ |
| 3 | Non-inverting input of Amplifier 1 | High-impedance JFET node; common-mode range includes VCC+ |
| 4 | Negative supply (VCC–) | Reference for both amplifiers; must be decoupled locally with 0.1 μF ceramic |
| 5 | Non-inverting input of Amplifier 2 | Independent high-Z input; electrically isolated from Amp 1 except via shared supply |
| 6 | Inverting input of Amplifier 2 | Matched to Pin 2; supports dual-channel differential or parallel configurations |
| 7 | Output of Amplifier 2 | Identical drive capability to Pin 1; no crosstalk specification beyond 1 µV/V at DC |
| 8 | Positive supply (VCC+) | Power rail for both amplifiers; requires local 0.1 μF + 10 μF bulk decoupling |

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 temperature range (0°C to 70°C vs –40°C to +85°C); higher max input offset (10 mV) | Not rated for extended industrial ambient; less suitable for outdoor solar or factory-floor motor drives | Select TL082CDR only for cost-sensitive commercial-grade designs where temperature extremes are absent |
| OPA2134PA | Higher precision (500 μV max VOS), lower noise (8 nV/√Hz), but higher quiescent current (4 mA/ch) and ±18 V max supply | Better for ultra-low-noise audio; unsuitable for 40 V rail systems or battery-constrained designs | Choose OPA2134PA when THD+N <0.0005% and sub-10 nV/√Hz noise are mandatory, and power budget allows |
Compared with TL082CDR, TL082ACPSR offers superior temperature stability and lower offset for industrial deployments; versus OPA2134PA, it trades noise performance for wider supply range and lower power - making it optimal for ruggedized, cost-efficient dual-op-amp signal chains.

FAQ
What is the maximum supply voltage for TL082ACPSR?
The TL082ACPSR supports a total supply voltage (VCC+ to VCC–) of up to 40 V, corresponding to ±20 V dual supplies or 40 V single-ended operation. Absolute maximum ratings specify 42 V for non-NS/PS packages, but TI recommends staying within 40 V for reliable long-term performance per the Recommended Operating Conditions table.
Does TL082ACPSR include ESD protection?
Yes, TL082ACPSR features integrated ESD protection rated at ±1500 V HBM (Human Body Model) and ±1000 V CDM (Charged Device Model), as confirmed in Section 5.2 of the official datasheet. This level meets standard industrial handling requirements and eliminates need for external ESD diodes in most PCB layouts.
Can TL082ACPSR drive capacitive loads?
TL082ACPSR is specified to safely drive up to 300 pF capacitive loads without oscillation, per its Electrical Characteristics table. For loads exceeding 300 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to maintain phase margin above 56° and prevent peaking or instability.
What is the input common-mode voltage range of TL082ACPSR?
The TL082ACPSR supports a common-mode input voltage range from (VCC–) + 1.5 V to VCC+, meaning its inputs operate up to and including the positive supply rail. This rail-to-rail input capability simplifies single-supply design and eliminates need for level-shifting in many sensor interface applications.
Is TL082ACPSR pin-compatible with other TL082 variants?
Yes, TL082ACPSR uses the industry-standard SOIC-8 pinout defined for all TL082x dual op-amps (e.g., TL082CDR, TL082IDR). Pins 1–8 map identically across variants, enabling direct substitution in existing layouts - provided thermal and electrical operating conditions (e.g., temperature grade, supply range) remain within spec.
