Product details
Overview
TL081HIDBVR from Texas Instruments is a single-channel JFET-input operational amplifier optimized for precision, high-speed analog signal conditioning in industrial and power electronics. It delivers 20 V/μs slew rate, 1 mV typical input offset voltage, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V dual-supply operation, and rail-to-rail common-mode input range extending to VCC+. It is used in solar inverter feedback loops, motor drive current sensing, and battery test equipment front-ends.
For engineers reviewing the TL081HIDBVR datasheet, TL081HIDBVR pinout, TL081HIDBVR application, or TL081HIDBVR equivalent, this page provides verified electrical specifications, SOT-23-5 package layout, real-world use cases in rugged power systems, and validated alternative options for design continuity and sourcing flexibility.
Technical Context
The TL081HIDBVR employs a JFET-input differential pair with high-impedance, low-bias-current architecture enabling wide common-mode range (including VCC+) and sub-nA input bias current (±1 pA typ). Its internal compensation ensures stable unity-gain operation with up to 300 pF capacitive load drive.
It features integrated EMI/RF filters and 1.5 kV HBM ESD protection, supporting reliable operation across –40°C to +125°C ambient. The device maintains 125 dB open-loop gain and 5.25 MHz gain-bandwidth product under full supply (40 V) and temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables accurate reproduction of fast-changing signals like PWM edge detection or transient current monitoring. |
| Input Offset Voltage | ±1 mV (typ) - supports high-accuracy DC-coupled amplification in sensor interfaces and precision reference buffers. |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - critical for low-noise signal conditioning in audio mixers and battery impedance measurement. |
| Supply Voltage Range | ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended) - accommodates wide industrial supply rails including 24 V and 36 V systems. |
| Common-Mode Input Range | Extends to VCC+ - allows direct sensing of high-side signals without level-shifting in motor phase current monitoring. |
| Quiescent Current | 940 μA/ch (typ) - balances performance and power efficiency in always-on instrumentation stages. |
| Gain-Bandwidth Product | 5.25 MHz - supports stable closed-loop gain ≥10 at >500 kHz for active filtering and signal reconstruction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL081CDR | Lower ESD rating (1 kV HBM), wider offset (±3 mV max), no integrated EMI filters, rated only to 85°C. | Not qualified for 125°C industrial enclosures or high-EMI motor drive zones. | Select when cost sensitivity outweighs temperature/EMI requirements and legacy designs require drop-in compatibility. |
| OPA1611AIDBVR | Lower noise (1.1 nV/√Hz), lower distortion (0.000015%), higher quiescent current (3.6 mA), no short-circuit protection. | Optimized for studio-grade audio; lacks robustness for power electronics fault conditions. | Choose for ultra-low-noise audio paths where thermal and ESD margins are secondary to signal purity. |
Compared with TL081CDR, TL081HIDBVR offers superior temperature range and EMI resilience for power conversion; versus OPA1611AIDBVR, it trades audio-grade noise performance for ruggedized protection and lower power-making it optimal for industrial signal conditioning where reliability trumps ultimate fidelity.

FAQ
What is the maximum supply voltage for TL081HIDBVR?
The TL081HIDBVR supports a total supply voltage (VCC+ to VCC–) of up to 40 V, corresponding to ±20 V dual supply or 4.5 V to 40 V single-ended operation. Absolute maximum ratings allow 42 V briefly, but recommended operating conditions specify 4.5 V to 40 V for sustained reliability. Exceeding 40 V risks parametric shift and reduced lifetime, especially at high temperature.
Does TL081HIDBVR support rail-to-rail input?
TL081HIDBVR supports rail-to-rail common-mode input range extending to VCC+, but not to VCC–. The minimum common-mode voltage is (VCC–) + 1.5 V at 25°C. This enables high-side sensing without level shifting, but low-side signals near VCC– require careful biasing or external clamping to avoid input stage saturation.
What is the thermal resistance (RθJA) of TL081HIDBVR in its SOT-23-5 package?
The TL081HIDBVR in DBV (SOT-23-5) package has a junction-to-ambient thermal resistance (RθJA) of 212.2°C/W under standard JEDEC test conditions. This value assumes 1-inch² 2-oz copper on a single-layer board; actual board layout significantly impacts thermal performance-adding thermal vias under the exposed pad can reduce RθJA by up to 40%.
Can TL081HIDBVR drive a 2-kΩ load while maintaining specified output swing?
Yes. At VS = 40 V, TL081HIDBVR delivers ±10 V output swing into RL ≥ 2 kΩ, with positive rail headroom of 520–965 mV and negative rail headroom of 500–1030 mV. This meets the requirement for driving standard 12-bit SAR ADC inputs and analog comparators without external buffering in industrial I/O modules.
Is TL081HIDBVR pin-compatible with older TL081 variants in SOT-23?
Yes. TL081HIDBVR uses the same 5-pin SOT-23 (DBV) pinout as TL081CDBVR and TL081ACDBVR: Pin 1 = IN+, Pin 2 = IN–, Pin 3 = VCC–, Pin 4 = OUT, Pin 5 = VCC+. No PCB changes are required when upgrading from legacy TL081C/AC versions to TL081HIDBVR for improved temperature range and EMI performance.
