Product details
Overview
TL071ID from STMicroelectronics is a low-noise JFET-input single operational amplifier designed for precision analog signal conditioning in audio, instrumentation, and sensor interface circuits. It delivers 16 V/µs slew rate, 15 nV/√Hz input voltage noise (typ), 80 dB CMRR, ±11 V input common-mode range, and operates from ±6 V to ±18 V supply rails.
For engineers reviewing the TL071ID datasheet, TL071ID pinout, TL071ID application, or TL071ID equivalent, key selection criteria include JFET-input bias current (≤20 pA typ), output short-circuit protection, internal frequency compensation, and SO-8 package compatibility with high-impedance source interfaces.
Technical Context
The TL071ID integrates matched high-voltage JFET and bipolar transistors on a monolithic die to achieve low input bias current and high input impedance (>10¹² Ω). Its fully differential JFET input stage enables rail-to-rail common-mode operation up to ±11 V with ±15 V supplies.
Internal frequency compensation ensures unity-gain stability without external components. The device supports output short-circuit protection indefinitely under thermal limits and exhibits 0.01% THD at 1 kHz with 2 Vpp output into 2 kΩ load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±6 V to ±18 V - supports dual-rail industrial and audio systems with headroom for ±12 V and ±15 V designs |
| Slew Rate | 16 V/µs (typ) - enables faithful reproduction of fast transients in active filters and audio preamps |
| Input Noise | 15 nV/√Hz (typ, 1 kHz) - critical for low-level sensor amplification where noise floor dominates SNR |
| Input Bias Current | 20 pA (typ, +25°C) - preserves signal integrity in high-impedance photodiode or piezoelectric sensor interfaces |
| CMRR | 80 dB (min) - rejects common-mode interference in differential measurement front-ends |
| Gain Bandwidth | 2.5 MHz (min) - supports stable closed-loop gain ≥10 at audio frequencies up to 250 kHz |
| THD | 0.01% (typ, 1 kHz) - meets fidelity requirements for line-level audio signal paths |
Pinout & Package
TL071ID is housed in an SO-8 plastic micropackage (JEDEC MS-012AC), 4.9 mm × 6.0 mm body, 1.27 mm pitch, with gull-wing leads and lead-free finish compliant with ECOPACK® standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null 1 | Connects to external 100 Ω–100 kΩ potentiometer wiper for fine-tuning input offset voltage |
| 2 | Inverting Input | High-impedance JFET gate node; accepts feedback network for inverting amplifier configurations |
| 3 | Non-inverting Input | High-impedance JFET gate node; used for buffer, summing, or differential input topologies |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally to minimize noise coupling |
| 5 | Offset Null 2 | Second terminal of offset null potentiometer; completes trimming circuit with Pin 1 |
| 6 | Output | Class-AB output stage capable of ±10 V swing into 2 kΩ load; short-circuit protected |
| 7 | VCC+ | Positive supply rail connection; requires local 100 nF ceramic decoupling capacitor |
| 8 | N.C. | No internal connection; electrically isolated; may be left floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | 20 pA typical enables use with >1 MΩ source impedances without significant DC error |
| High slew rate | 16 V/µs supports wideband applications including active filters and pulse amplifiers |
| Low harmonic distortion | 0.01% THD at 1 kHz ensures minimal spectral contamination in audio signal chains |
| Output short-circuit protection | Indefinite short-circuit capability simplifies system-level fault tolerance design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CP | DIP8 package, 0°C to +70°C temp range, identical electrical specs except wider Vio max (13 mV vs. 10 mV) | Suitable for cost-sensitive commercial PCBs where through-hole assembly is preferred | Select when board assembly uses wave soldering and ambient temperature stays within 0–70°C |
| OPA134UA | Lower noise (8 nV/√Hz), higher GBW (8 MHz), no offset null pins, SO-8 package | Better suited for ultra-low-noise audio paths but lacks trim capability for precision DC offsets | Choose when noise performance is prioritized over offset adjustability and DC precision |
Compared with TL071CP, TL071ID offers automotive-grade temperature range (−40°C to +105°C) and surface-mount compatibility; versus OPA134UA, it trades lower noise for offset trimming flexibility and robust short-circuit protection-critical in industrial sensor front-ends.

FAQ
What is the maximum supply voltage for TL071ID?
The absolute maximum supply voltage is ±18 V. Operation beyond this risks permanent damage. For reliable long-term use, ST recommends staying within ±15 V, especially at elevated temperatures, to maintain thermal safety margins and ensure output short-circuit protection remains effective under worst-case dissipation conditions.
Does TL071ID require external compensation capacitors?
No. TL071ID features internal frequency compensation optimized for unity-gain stability across its full operating range. Adding external compensation is unnecessary and may degrade bandwidth or phase margin. This simplifies design in standard inverting/non-inverting configurations without compromising stability.
Can TL071ID drive a 600 Ω audio load directly?
No. TL071ID specifies output swing into 2 kΩ and 10 kΩ loads only. Driving 600 Ω risks excessive current draw, thermal overload, and reduced voltage swing due to output stage limitations. For 600 Ω interfacing, use a dedicated line driver IC or add a discrete emitter-follower buffer stage.
How is offset voltage adjusted on TL071ID?
Offset voltage is trimmed using Pins 1 and 5 (Offset Null 1 and Offset Null 2) with a 10 kΩ potentiometer connected between them and VCC−. The wiper connects to VCC+ (or VCC− depending on polarity); adjustment minimizes output DC error at the specified operating temperature and supply condition.
