Product details
Overview
TL082BCPG4 from Texas Instruments is a dual JFET-input operational amplifier designed for precision analog signal conditioning in industrial and audio systems. It delivers 20 V/μs slew rate, ±1 mV input offset voltage (typ), 5.25 MHz gain-bandwidth product, and operates from ±2.25 V to ±20 V supplies. It serves as a high-speed, low-noise gain stage in pro audio mixers and battery test equipment.
For engineers reviewing the TL082BCPG4 datasheet, TL082BCPG4 pinout, TL082BCPG4 application, or TL082BCPG4 equivalent, this page provides verified electrical specs, SOIC-8 package details, dual-channel functional context, and validated alternatives for cost-sensitive, wide-supply-rail designs requiring FET-input performance.
Technical Context
The TL082BCPG4 implements a dual-channel, high-slew-rate JFET-input op-amp architecture with rail-to-rail common-mode input range extending to VCC+, enabling operation in single-supply configurations up to +40 V. Its differential pair input stage ensures ultra-low input bias current (±1 pA typ) and low noise (37 nV/√Hz at 1 kHz).
It features internal frequency compensation for unity-gain stability, output short-circuit protection, and EMI/RF filtering. The device supports full industrial temperature range (–40°C to +125°C) and meets 1.5 kV HBM ESD rating, making it suitable for motor drive feedback loops and UPS control circuits where robustness and precision coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent amplifiers - enables compact two-stage signal conditioning or differential pair implementation without external matching. |
| Slew Rate | 20 V/μs (typ) - supports clean amplification of fast transients in audio and power-conversion feedback paths. |
| Input Offset Voltage | ±1 mV (typ) - minimizes DC error in precision sensor interfaces and battery voltage monitoring circuits. |
| Gain-Bandwidth Product | 5.25 MHz - allows stable closed-loop gain ≥10 at 500 kHz, suitable for active filters and anti-aliasing stages. |
| Supply Voltage Range | ±2.25 V to ±20 V (or 4.5 V to 40 V single supply) - accommodates legacy ±15 V systems and modern wide-range industrial rails. |
| Input Bias Current | ±1 pA (typ) - preserves signal integrity in high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes. |
| Common-Mode Input Range | Extends to VCC+ - permits direct sensing of signals near positive rail, e.g., high-side current shunt monitoring. |
Pinout & Package
TL082BCPG4 is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package (package code D), with standard pinout compatible across TL082x family variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output of Amplifier 1 | Delivers amplified, buffered signal; capable of sourcing/sinking ±26 mA with 210 mV headroom to positive rail (VS = 40 V, RL = 10 kΩ). |
| 1IN– | Inverting Input of Amplifier 1 | Accepts feedback network connection; high-impedance node (6 TΩ || 1 pF) minimizes loading on preceding stage. |
| 1IN+ | Non-inverting Input of Amplifier 1 | High-Z input for reference or sensor signal; common-mode range includes VCC+, enabling single-supply level-shifting. |
| VCC– | Negative Supply Rail | Reference for dual-supply operation; also used as ground reference in single-supply configurations with virtual ground. |
| 2IN+ | Non-inverting Input of Amplifier 2 | Independent second channel input; identical electrical characteristics to Channel 1 for matched dual-path designs. |
| 2IN– | Inverting Input of Amplifier 2 | Supports independent feedback configuration per channel; no crosstalk between channels (1 µV/V typical separation). |
| 2OUT | Output of Amplifier 2 | Provides second gain path; same AC/DC performance as 1OUT - critical for stereo audio or dual-sensor readout. |
| VCC+ | Positive Supply Rail | Accepts up to +40 V; internal EMI/RF filtering improves immunity in noisy motor drive or inverter environments. |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ±1 pA typical enables use with >1 GΩ source impedances without significant DC error or drift. |
| High Slew Rate | 20 V/μs ensures faithful reproduction of fast edges in PWM-based motor control feedback loops. |
| Wide Common-Mode Range | Includes VCC+, allowing direct interface to signals referenced to positive rail - eliminates need for level-shifting circuitry. |
| EMI/RF Filtering | Integrated filters suppress 1 GHz interference, improving reliability in solar inverter and UPS EMI-heavy environments. |
| Output Short-Circuit Protection | Withstands indefinite short to ground per amplifier - enhances system safety in unattended industrial equipment. |

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 (±3 mV max vs ±4 mV for TL082BCPG4), lower ESD rating (1 kV HBM), commercial temp range (0°C to 70°C). | Not rated for industrial ambient (–40°C to +125°C); unsuitable for outdoor solar or automotive-adjacent motor drives. | Select TL082CDR only for cost-optimized, indoor, room-temperature applications with relaxed DC accuracy. |
| OPA2134PA | Higher precision (±0.5 mV offset, 8 MHz GBW), lower noise (8 nV/√Hz), but higher quiescent current (4 mA/ch) and no integrated EMI filtering. | Lacks built-in RF suppression; requires external filtering in noisy inverter or UPS PCB layouts. | Choose OPA2134PA when ultra-low distortion (<0.00008%) and bandwidth outweigh EMI robustness and power efficiency. |
Compared with TL082CDR, TL082BCPG4 offers superior temperature range and ESD tolerance for harsh environments; versus OPA2134PA, it trades some precision and noise performance for lower power (940 μA/ch) and inherent EMI resilience - ideal for industrial-grade signal chains where reliability and supply flexibility are prioritized.

FAQ
What is the maximum supply voltage for TL082BCPG4?
The TL082BCPG4 supports a total supply voltage range of ±2.25 V to ±20 V (dual supply) or 4.5 V to 40 V (single supply). Absolute maximum ratings specify 42 V for most packages, but recommended operating conditions limit continuous operation to 40 V to ensure long-term reliability and specified performance across temperature.
Does TL082BCPG4 have rail-to-rail input capability?
Yes, TL082BCPG4 features a common-mode input voltage range that extends to VCC+, satisfying rail-to-rail input functionality on the positive side. However, the lower bound is (VCC–) + 1.5 V, so it does not swing fully to the negative rail - making it single-supply compatible but not true rail-to-rail on both ends.
Is TL082BCPG4 pin-compatible with other TL082 variants in SOIC-8?
Yes, TL082BCPG4 uses the standard TL082x SOIC-8 pinout (pin 1 = 1OUT, pin 2 = 1IN–, etc.) and is mechanically and electrically pin-compatible with all TL082x variants in the D package, including TL082CDR and TL082IDR, enabling drop-in replacement within the same temperature and accuracy grade constraints.
What is the typical input bias current of TL082BCPG4?
The typical input bias current of TL082BCPG4 is ±1 pA at 25°C, measured under standard test conditions (VS = ±15 V). This ultra-low value is enabled by its JFET input stage and remains below ±120 pA over the full –40°C to +125°C operating range, supporting high-impedance sensor interfaces.
Can TL082BCPG4 drive capacitive loads?
TL082BCPG4 is characterized for stable operation with up to 300 pF capacitive load. For larger loads, 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 oscillation in closed-loop configurations.
