Product details
Overview
TL082ACD 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 TL082ACD datasheet, TL082ACD pinout, TL082ACD application, or TL082ACD equivalent, this page provides verified specifications, SOIC-8 package details, real-world use cases in UPS and battery test equipment, and two validated alternative parts with documented functional and thermal differences.
Technical Context
The TL082ACD uses dual JFET input stages to achieve ultra-low input bias current (≤200 pA) and high input impedance (>1 TΩ), supporting accurate sensing in high-impedance source applications like piezoelectric transducers and photodiode amplifiers. Its internal compensation ensures stable unity-gain operation with capacitive loads up to 300 pF.
It operates across ±2.25 V to ±20 V supplies, features rail-to-rail common-mode input range including VCC+, and integrates EMI/RF filters for robustness in electrically noisy environments such as solar inverters and AC motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±2.25 V to ±20 V - supports single-supply (4.5–40 V) or split-rail operation without level-shifting circuitry |
| Gain-Bandwidth Product | 5.25 MHz - enables stable closed-loop gain of 10 at 500 kHz for anti-aliasing or active filtering |
| Slew Rate | 20 V/μs - preserves transient fidelity in fast step-response applications like PWM current sensing |
| Input Offset Voltage | 3–10 mV (typ 6 mV) - sets DC accuracy limit in non-inverting amplifier configurations with gain ≥10 |
| Common-Mode Rejection | 70–100 dB - suppresses power-supply noise and ground bounce in differential measurement front-ends |
| Input Bias Current | 65–200 pA - minimizes voltage error across high-value feedback resistors (>1 MΩ) |
| Quiescent Current | 1.4–2.5 mA per amplifier - balances low-power operation with bandwidth requirements in portable test gear |
Pinout & Package
TL082ACD is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package, surface-mount compatible with standard reflow profiles and IPC-7351B land patterns. The package measures 4.9 mm × 3.9 mm × 1.75 mm (L × W × H) with 1.27 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output of Amplifier 1 | Drives external load or next-stage input; capable of ±12 V swing into 10 kΩ at ±15 V supply |
| 1IN− | Inverting Input of Amplifier 1 | Accepts feedback network connection; high-impedance node sensitive to PCB leakage and guarding |
| 1IN+ | Non-inverting Input of Amplifier 1 | High-Z input for reference or sensor signal; common-mode range extends to VCC+ rail |
| VCC− | Negative Supply Rail | Reference for both amplifiers; must be decoupled with 0.1 μF ceramic capacitor near pin |
| 2IN+ | Non-inverting Input of Amplifier 2 | Independent input for second channel; no crosstalk with Channel 1 below 100 kHz |
| 2IN− | Inverting Input of Amplifier 2 | Supports independent feedback configuration; shares same input stage architecture as Channel 1 |
| 2OUT | Output of Amplifier 2 | Provides matched AC performance to Channel 1; output short-circuit protected to ±26 mA |
| VCC+ | Positive Supply Rail | Power for both amplifiers; EMI filtering integrated to reject 1 GHz interference per EMIRR = 53 dB |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Enables ≤200 pA input bias current for minimal loading of high-impedance sensors and passive filters |
| Wide common-mode input range | Includes VCC+ rail, allowing direct interface with unbuffered DAC outputs or rail-referenced signals |
| Integrated EMI/RF filters | Provides 53 dB rejection at 1 GHz, reducing susceptibility in switch-mode power supply environments |
| Output short-circuit protection | Limits fault current to ±26 mA, preventing thermal runaway during accidental output-to-rail shorts |

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 and pinout; wider temperature range (0°C to 70°C vs –40°C to 85°C for TL082ACD); higher max input offset (13 mV) | Lower-cost option for commercial-grade designs where extended temperature operation is not required | Select TL082CDR when cost sensitivity outweighs need for industrial temperature grade and tighter offset spec |
| OPA2134PA | Higher precision (250 μV max offset), lower noise (8 nV/√Hz), but higher quiescent current (4 mA/ch) and no integrated EMI filtering | Preferred for audio-grade preamps and medical instrumentation requiring superior SNR and DC accuracy | Choose OPA2134PA only when system-level EMI immunity is handled externally and sub-mV offset is mandatory |
Compared with TL082CDR, TL082ACD offers better temperature stability and lower offset drift; versus OPA2134PA, it trades noise performance for integrated EMI resilience and lower power - making TL082ACD optimal for ruggedized industrial signal chains where cost and reliability dominate.

FAQ
What is the maximum operating temperature range for TL082ACD?
The TL082ACD is rated for operation from –40°C to +85°C ambient temperature, meeting industrial-grade environmental requirements. This range is confirmed in Section 5.3 "Recommended Operating Conditions" of the official Texas Instruments datasheet (SLOS081O, September 2025 revision), where TA = –40°C to 85°C is specified for the TL082ACD variant. Exceeding this range may degrade offset voltage drift and CMRR performance.
Does TL082ACD support single-supply operation?
Yes, TL082ACD supports true single-supply operation from 4.5 V to 40 V. Its common-mode input voltage range extends to VCC+, enabling direct interfacing with unbuffered single-supply DACs or sensors referenced to VCC. This capability is explicitly documented in the "Input Voltage Range" specification (Section 5.3) and verified in Figure 5-4 through 5-6 of the TL082ACD datasheet.
What is the typical input offset voltage for TL082ACD?
The typical input offset voltage for TL082ACD is 6 mV, with a guaranteed maximum of 10 mV at 25°C and full-range maximum of 13 mV (TA = –40°C to +85°C). These values are specified in Table 5.8 "Electrical Characteristics (DC)" of the TI datasheet, under the TL082ACD row (listed as TL082A). The offset drift is ±18 µV/°C across temperature.
Can TL082ACD drive capacitive loads?
Yes, TL082ACD can safely drive capacitive loads up to 300 pF while maintaining stability, as confirmed by the "Capacitive Load Drive" parameter (CLOAD = 300 pF) in Section 5.7 of the datasheet. For loads exceeding 300 pF, external series resistance (e.g., 10–50 Ω) at the output is recommended to prevent peaking or oscillation, especially in unity-gain configurations.
Is TL082ACD pin-compatible with other TL082 variants?
Yes, TL082ACD is pin-compatible with all TL082x devices in SOIC-8 (D) package, including TL082CDR, TL082IDR, and TL082CP. Pin functions match Table 4-3 in the datasheet: Pins 1/7 = outputs, 2/6 = inverting inputs, 3/5 = non-inverting inputs, 4 = VCC−, 8 = VCC+. No PCB layout changes are required when substituting within the same SOIC-8 footprint.
