Product details
Overview
TL082CDRE4 from Texas Instruments is a dual JFET-input operational amplifier optimized for precision AC and DC signal conditioning in industrial and audio systems. It delivers 20 V/μs slew rate, 5.25 MHz gain-bandwidth product, ±1 mV input offset voltage (typ), 105 dB common-mode rejection ratio, and operates from ±2.25 V to ±20 V supplies. Used in pro audio mixers and battery test equipment where low noise and rail-to-rail input capability are critical.
For engineers reviewing the TL082CDRE4 datasheet, TL082CDRE4 pinout, TL082CDRE4 application, or TL082CDRE4 equivalent, this page provides verified electrical specs, SOIC-8 package layout, dual-channel FET-input architecture details, and validated alternatives for cost-sensitive analog signal chains requiring high CMRR and low IB.
Technical Context
The TL082CDRE4 implements a dual-channel, high-slew-rate JFET-input op-amp topology with fully differential input stage and Class AB output stage. Its input stage supports common-mode voltage up to VCC+, enabling single-supply operation with proper biasing. The device uses internal compensation for unity-gain stability with ≥5.25 MHz GBW and 56° phase margin at 10 kΩ load and 20 pF capacitance.
It features integrated EMI/RF filters and 1.5 kV HBM ESD protection. Quiescent current is 937.5–1125 μA per channel, and output short-circuit protection limits current to ±26 mA. Input bias current remains below 120 pA (typ) across –40°C to +125°C, supporting high-impedance sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent amplifiers - enables stereo audio paths or dual feedback loops without inter-channel crosstalk degradation |
| Slew Rate | 20 V/μs (typ) - supports clean 10 Vpp signals up to ~300 kHz before slew-induced distortion dominates |
| Gain-Bandwidth | 5.25 MHz - allows stable closed-loop gain of 100 at 52.5 kHz or unity gain at 5.25 MHz |
| Input Offset Voltage | ±1 mV (max at 25°C) - ensures ≤10 mV error in 10 V full-scale measurement circuits |
| CMRR | 105 dB (min) - rejects >3 million:1 common-mode interference, critical in noisy motor drive environments |
| Supply Range | ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended) - accommodates legacy ±15 V rails and modern low-voltage systems |
| Input Bias Current | ±120 pA (typ) - preserves signal integrity when driving from MΩ-level source impedances (e.g., piezoelectric sensors) |
Pinout & Package
TL082CDRE4 is supplied in an 8-pin SOIC (D) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). Pin 1 is marked by a beveled corner or dot; orientation follows TI's top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output of Amplifier 1 | Class AB push-pull output capable of sourcing/sinking ±26 mA; requires external load ≥2 kΩ for full swing |
| 1IN– | Inverting Input of Amp 1 | JFET-differential pair input; high impedance (6 TΩ || 1 pF), supports common-mode range to VCC+ |
| 1IN+ | Non-inverting Input of Amp 1 | Matched to 1IN–; used for unity-gain buffers or non-inverting configurations with minimal offset error |
| VCC– | Negative Supply Rail | Reference for both amplifiers; must be decoupled with ≥0.1 μF ceramic capacitor near pin |
| 2IN+ | Non-inverting Input of Amp 2 | Electrically isolated from Amp 1 inputs; enables independent dual-channel signal processing |
| 2IN– | Inverting Input of Amp 2 | Same JFET input structure as 1IN–; channel separation >100 dB prevents coupling in sensitive instrumentation |
| 2OUT | Output of Amplifier 2 | Identical performance to 1OUT; no shared output stage - avoids thermal crosstalk in dual-output designs |
| VCC+ | Positive Supply Rail | Accepts up to +20 V; internal EMI filtering reduces RF susceptibility above 100 MHz |
Key Features
| Feature | Design Value |
|---|---|
| High Slew Rate (20 V/μs) | Enables faithful reproduction of fast transients in audio and control loop applications without slew-induced distortion |
| Low Input Bias Current (120 pA typ) | Maintains accuracy in high-Z sensor interfaces (e.g., pH electrodes, photodiode TIA feedback networks) |
| Wide Common-Mode Range (to VCC+) | Permits single-supply operation with input signals referenced to ground while preserving dynamic range |
| Integrated EMI/RF Filters | Reduces susceptibility to GSM, Wi-Fi, and switching regulator noise without external ferrite beads |
| Output Short-Circuit Protection | Prevents latch-up or permanent damage during accidental shorts - eliminates need for external current-limiting resistors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082IDR | Same SOIC-8 package; rated for –40°C to +85°C (vs. TL082CDRE4's 0°C to 70°C industrial temp grade) | Preferred for extended temperature environments like outdoor solar inverters or automotive-adjacent industrial controls | Select TL082IDR when operating above 70°C ambient or requiring wider guaranteed offset drift spec (±2 μV/°C vs. ±18 μV/°C for C-grade) |
| OPA2134PA | Lower noise (8 nV/√Hz), lower IB (1 pA), but higher quiescent current (4 mA/ch) and higher cost; DIP-8 only | Better suited for ultra-low-noise audio front-ends where power budget allows; not drop-in due to different pinout and supply sensitivity | Choose OPA2134PA only when noise floor <10 nV/√Hz is mandatory and PCB redesign is acceptable |
Compared with TL082IDR and OPA2134PA, TL082CDRE4 offers optimal balance of cost, speed, and industrial temperature compliance - delivering 20 V/μs slew rate and 5.25 MHz GBW at lowest unit price among TI's dual JFET op-amps in SOIC-8.

FAQ
What is the maximum supply voltage for TL082CDRE4?
The TL082CDRE4 supports a total supply voltage range of ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended). Absolute maximum ratings specify 42 V for all devices except NS/PS packages and TL08xM variants, which are limited to 36 V. Operation beyond these limits risks permanent damage.
Does TL082CDRE4 have rail-to-rail input capability?
Yes - the TL082CDRE4 features a JFET-input stage with common-mode input voltage range extending to VCC+, enabling true rail-to-rail input operation when VCC– is grounded. This allows use in single-supply configurations with input signals referenced to ground without loss of dynamic range.
What is the typical input offset voltage drift of TL082CDRE4?
The TL082CDRE4 exhibits a typical input offset voltage drift of ±2 μV/°C over the full industrial temperature range (–40°C to +125°C). This low drift ensures minimal calibration drift in precision measurement systems operating across wide ambient temperatures.
Can TL082CDRE4 drive capacitive loads?
Yes - the TL082CDRE4 is specified to drive up to 300 pF capacitive load while maintaining stability. For loads >20 pF, phase margin drops below 56°, so external series resistance (e.g., 10–100 Ω) is recommended between output and capacitive load to prevent peaking or oscillation.
Is TL082CDRE4 pin-compatible with other TL082 variants?
Yes - TL082CDRE4 uses the standard SOIC-8 (D) package with identical pinout to TL082IDR, TL082CP, and TL082ACDR. All share the same 1OUT/1IN–/1IN+/VCC–/2IN+/2IN–/2OUT/VCC+ arrangement, enabling direct substitution within the same temperature grade constraints.
