Product details
Overview
TL082CPW 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, low 37 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail common-mode input range extending to VCC+. It is used in pro audio mixers and battery test equipment where low distortion (0.003% THD+N) and high CMRR (100 dB) are critical.
For engineers reviewing the TL082CPW datasheet, TL082CPW pinout, TL082CPW application, or TL082CPW equivalent, this page provides verified specifications, TSSOP-8 package layout, dual-channel FET-input amplifier functionality, offset voltage drift (±2 μV/°C), and real-world use cases in motor drive feedback loops and UPS control circuits - all confirmed against TI's SLOS081O production data sheet (September 2025 revision).
Technical Context
The TL082CPW implements a dual-channel, high-slew-rate JFET-input op-amp architecture with fully differential inputs capable of common-mode voltage operation up to VCC+. Its internal compensation ensures stable unity-gain operation with capacitive loads up to 300 pF, and it features integrated EMI/RF filters plus 1.5 kV HBM ESD protection.
It operates across ±2.25 V to ±20 V (or 4.5 V to 40 V single-supply) with quiescent current of 1.4–2.5 mA per channel, output short-circuit protection, and no phase reversal under overload - enabling robust deployment in motor drive power stage monitoring and solar inverter sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.25 MHz - supports stable closed-loop amplification up to ~500 kHz at G = 10 without peaking |
| Slew rate | 20 V/μs - enables faithful reproduction of fast transients in audio and PWM-based control signals |
| Input voltage noise density | 37 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signal chains (e.g., thermocouple amplifiers) |
| Common-mode input range | VCC– + 1.5 V to VCC+ - allows direct sensing of signals referenced to positive rail (e.g., high-side current sensing) |
| CMRR | 100 dB (min) - rejects power supply ripple and ground noise in noisy industrial environments |

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 |
|---|---|---|---|
| TL082IPW | Rated for –40°C to +85°C industrial temperature range; identical pinout and electrical specs except wider temp grade | Preferred for extended-temperature motor drives and outdoor UPS units | Select TL082IPW when ambient exceeds 70°C or when long-term reliability at temperature extremes is required |
| TL082CDR | SOIC-8 package (D), not TSSOP-8; same electrical performance but 3.9 mm × 4.9 mm footprint vs. 3.0 mm × 4.4 mm | Used where board space is less constrained and hand-soldering or legacy footprint compatibility is needed | Choose TL082CDR for through-hole prototyping, rework-friendly layouts, or cost-sensitive high-volume PCBs |
Compared with TL082CPW, TL082IPW offers broader temperature qualification while TL082CDR trades compact TSSOP packaging for SOIC manufacturability - both retain identical gain-bandwidth, noise, and CMRR, making them functionally interchangeable where thermal or mechanical constraints permit.

FAQ
What is the maximum supply voltage for TL082CPW?
The TL082CPW supports a total supply voltage (VCC+ − VCC−) of up to 40 V, corresponding to ±20 V dual-supply operation or 4.5 V to 40 V single-supply use. Absolute maximum ratings specify 42 V for non-NS/PS packages, but TI recommends staying within 40 V for reliable long-term operation per SLOS081O Section 5.1.
Does TL082CPW have rail-to-rail input capability?
Yes, the TL082CPW features a rail-to-rail common-mode input voltage range extending to VCC+, specifically (VCC−) + 1.5 V to VCC+. This allows direct interfacing with signals referenced to the positive supply rail - essential for high-side current sensing and single-supply sensor front-ends in TL082CPW-based designs.
What is the typical input offset voltage drift of TL082CPW?
The TL082CPW exhibits a typical input offset voltage drift of ±2 μV/°C over the full operating temperature range of 0°C to 70°C. This value is confirmed in TI's SLOS081O datasheet Section 5.7 under "dVOS/dT" for TL08xH devices, ensuring predictable DC error accumulation in precision integrators and sensor amplifiers using TL082CPW.
Can TL082CPW drive capacitive loads?
Yes, the TL082CPW is characterized to safely drive capacitive loads up to 300 pF while maintaining stability and specified phase margin (56°). This capability is documented in Section 5.7 of the SLOS081O datasheet under "CLOAD", enabling direct connection to ADC input filters or long cables without external isolation resistors in TL082CPW signal chains.
Is TL082CPW pin-compatible with other TL082 variants?
Yes, TL082CPW is pin-compatible with all TL082x variants in TSSOP-8 (PW), SOIC-8 (D), and PDIP-8 (P) packages. Pin functions - including 1OUT, 1IN−, 1IN+, VCC−, 2IN+, 2IN−, 2OUT, and VCC+ - match identically across these variants per Table 4-3 in SLOS081O, allowing drop-in replacement where package and temperature grade align.
