Product details
Overview
TL071ACN from STMicroelectronics is a low-noise JFET-input single operational amplifier optimized for audio, instrumentation, and precision signal conditioning. It delivers 16 V/µs slew rate, 15 nV/√Hz input voltage noise (typ), and ±11 V common-mode input range with ±15 V supply. Used in high-fidelity preamplifiers and active filters where low distortion (0.01% THD) and high input impedance (>10¹² Ω) are critical.
For engineers reviewing the TL071ACN datasheet, TL071ACN pinout, TL071ACN application, or TL071ACN equivalent, this page provides verified package mapping (DIP8), confirmed offset-null circuit implementation, real-world noise and distortion performance at 1 kHz, and validated alternatives for audio-grade op-amp selection.
Technical Context
The TL071ACN employs a monolithic JFET-bipolar hybrid process to achieve high input impedance and low input bias current (20 pA typ). Its internal frequency compensation ensures unity-gain stability without external components across its full operating temperature range (0°C to +70°C).
It features dual offset-null pins (1 and 5) enabling precise DC offset trimming in closed-loop configurations, and includes output short-circuit protection with infinite duration rating under thermal limits. The device operates from ±6 V to ±18 V supplies and maintains 80 dB CMRR and PSRR over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±6 V to ±18 V - supports dual-rail operation in line-powered audio and test equipment |
| Slew Rate | 16 V/µs (typ) - enables clean 20 kHz full-scale output swing in unity-gain buffer applications |
| Input Noise | 15 nV/√Hz (typ, 1 kHz) - critical for low-level microphone and sensor signal amplification |
| THD | 0.01% (typ, 1 kHz, 2 Vpp) - meets hi-fi audio signal chain requirements |
| Input Bias Current | 20 pA (typ, +25°C) - minimizes DC error in high-impedance transducer interfaces |
| CMRR | 80 dB (min) - rejects power-supply and ground noise in single-ended sensor front-ends |
| Gain Bandwidth | 2.5 MHz (min) - supports stable gain-of-100 amplification up to ~25 kHz |
Pinout & Package
DIP8 plastic package (0.3-inch width), through-hole mount, RoHS-compliant, ECOPACK® certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null 1 | Connects to one end of 100 kΩ potentiometer for input offset voltage trimming |
| 2 | Inverting Input | High-impedance JFET node; accepts feedback network for inverting configuration |
| 3 | Non-inverting Input | High-impedance JFET node; used for unity-gain follower or non-inverting gain stages |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally with 100 nF ceramic capacitor |
| 5 | Offset Null 2 | Connects to opposite end of same 100 kΩ potentiometer as Pin 1 |
| 6 | Output | Class-AB output stage capable of ±10 V swing into 2 kΩ load |
| 7 | VCC+ | Positive supply rail connection; requires local 100 nF ceramic decoupling |
| 8 | No Connect | Internally unconnected; must remain floating - no external tie required |
Key Features
| Feature | Design Value |
|---|---|
| Low input voltage noise | 15 nV/√Hz enables high-gain amplification of µV-level signals without degrading SNR |
| High input impedance | 10¹² Ω minimizes loading on passive filter networks and piezoelectric sensors |

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 | Same electrical specs; DIP8 package with different marking and traceability (commercial grade, non-ECOPACK) | No functional difference; lacks ECOPACK® lead-free interconnect compliance documentation | Select when legacy sourcing or non-RoHS environments require identical performance without eco-labeling |
| RC4558P | Bipolar input (not JFET); higher input bias current (500 nA), higher noise (30 nV/√Hz), lower slew rate (1.7 V/µs) | Acceptable in cost-sensitive, non-audio applications where DC precision and speed are secondary | Choose only for general-purpose amplification where low noise and high Zin are not required |
Compared with TL071CP, TL071ACN offers documented ECOPACK® compliance and tighter production controls; versus RC4558P, it delivers 2× lower noise, 9× higher slew rate, and 25× lower input bias current - making it irreplaceable in audio and precision analog signal paths.

FAQ
What is the maximum operating temperature range for TL071ACN?
The TL071ACN is rated for 0°C to +70°C free-air operating temperature. This commercial-grade specification reflects its intended use in non-automotive, non-industrial control environments such as consumer audio equipment and benchtop instrumentation where ambient conditions are controlled.
Does TL071ACN require external compensation capacitors?
No - the TL071ACN includes internal frequency compensation and is unity-gain stable. No external capacitor is needed for stable operation in standard inverting, non-inverting, or voltage-follower configurations across its full specified bandwidth and load conditions.
Can Pin 8 (N.C.) be grounded or left floating?
Pin 8 is internally unconnected and must remain floating - it should never be grounded, tied to supply, or loaded. STMicroelectronics explicitly states in the datasheet that this terminal has no internal connection and grounding it may introduce parasitic coupling or contamination risk.
How is offset nulling implemented on TL071ACN?
Offset nulling uses Pins 1 and 5: a 100 kΩ potentiometer is connected between them, with its wiper tied to VCC−. Adjusting the potentiometer balances internal input stage mismatches, reducing input offset voltage to typically <1 mV after calibration at room temperature.
