Product details
Overview
TL072ACN from STMicroelectronics is a low-noise JFET-input dual operational amplifier in an 8-pin DIP package, featuring 16 V/µs slew rate, 15 nV/√Hz input voltage noise (typ), ±15 V common-mode input range, and 2.5–4 MHz gain-bandwidth product. It serves as a precision signal conditioning and audio amplification stage in analog front-ends requiring high input impedance and low harmonic distortion.
For engineers reviewing the TL072ACN datasheet, TL072ACN pinout, TL072ACN application, or TL072ACN equivalent, this page delivers verified electrical parameters, SO8-compatible DIP-8 pin mapping, real-world use cases in audio preamps and sensor interfaces, and validated alternatives with documented functional trade-offs.
Technical Context
The TL072ACN integrates two matched JFET-input op-amp channels on a single monolithic die, using high-voltage JFETs for input stages and bipolar transistors for output drivers. Its internal frequency compensation ensures unity-gain stability without external components.
It operates from ±6 V to ±18 V supply rails, supports rail-to-rail common-mode input up to ±11 V (with ±15 V supplies), and delivers ±12 V output swing into 10 kΩ loads. Channel separation exceeds 120 dB at Av = 100, minimizing crosstalk in dual-channel signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 16 V/µs (typ) - enables clean amplification of audio signals up to ~100 kHz without slew-induced distortion |
| Input Voltage Noise | 15 nV/√Hz (typ at 1 kHz) - critical for low-level sensor signal integrity in instrumentation |
| Input Bias Current | 20 pA (typ at +25°C) - preserves signal fidelity in high-impedance source networks (e.g., piezoelectric sensors) |
| Gain-Bandwidth Product | 2.5–4 MHz - supports stable closed-loop gains up to ~100 at 20 kHz for audio applications |
| Common-Mode Range | ±11 V (min) with ±15 V supplies - allows direct interfacing with bipolar sensor outputs and AC-coupled sources |
| Total Harmonic Distortion | 0.01 % (typ at 1 kHz, 2 Vpp) - meets Hi-Fi audio preamplifier linearity requirements |
| Supply Current per Channel | 1.4–2.5 mA - balances performance and power efficiency in dual-channel analog systems |
Pinout & Package
TL072ACN uses an 8-pin plastic DIP (Dual In-line Package) with 0.3-inch body width and 0.1-inch lead pitch, compatible with standard through-hole PCB layouts and socketing. The package provides thermal resistance of 125 °C/W (junction-to-ambient) under free-air conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output 1 | Amplified output of first op-amp channel; drives external load or feedback network |
| 2 | Inverting Input 1 | Negative input terminal of first op-amp; sets gain and phase response in inverting configurations |
| 3 | Non-inverting Input 1 | Positive input terminal of first op-amp; used in non-inverting buffers and summing junctions |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally to minimize noise coupling |
| 5 | Non-inverting Input 2 | Positive input terminal of second op-amp; enables independent dual-channel operation |
| 6 | Inverting Input 2 | Negative input terminal of second op-amp; supports stereo or differential pair topologies |
| 7 | Output 2 | Amplified output of second op-amp channel; electrically isolated from Output 1 except via substrate |
| 8 | VCC+ | Positive supply rail connection; requires local 100 nF ceramic decoupling capacitor |
Key Features
| Feature | Design Value |
|---|---|
| High Input Impedance | 10¹² Ω - prevents loading of high-Z sources like electret mics and photodiode transimpedance nodes |
| Output Short-Circuit Protection | Continuous safe shorting to either rail or ground - eliminates need for external current-limiting resistors |
| Latch-Up Free Operation | Guaranteed under all valid operating conditions - ensures reliability in mixed-signal PCB environments |
| Low Input Offset Drift | 10 µV/°C (max) - maintains DC accuracy across industrial temperature ranges without trimming |
| Internal Frequency Compensation | Unity-gain stable without external components - simplifies design and reduces BOM count |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CD | Same architecture but commercial-grade (0°C to +70°C); higher input offset voltage (3–10 mV vs. 3–6 mV) | Not rated for extended industrial temperature range; suitable only for benign ambient environments | Select when cost sensitivity outweighs temperature stability requirements and full-spec performance is not needed |
| OPA2134PA | FET-input dual op-amp with lower noise (8 nV/√Hz), lower THD (0.00008 %), but higher supply current (4 mA/channel) | Higher precision audio and measurement applications where power budget allows | Choose for ultra-low-noise studio-grade preamps or metrology systems where 15 nV/√Hz is insufficient |
Compared with TL072CD, TL072ACN offers tighter input offset voltage and extended temperature operation; versus OPA2134PA, it trades lower noise and distortion for significantly lower quiescent current and broader supply voltage tolerance (±18 V vs. ±15 V).

FAQ
What is the maximum supply voltage for TL072ACN?
The absolute maximum supply voltage is ±18 V, meaning total supply span must not exceed 36 V. Operation at ±15 V is typical and recommended for optimal noise and slew performance. Exceeding ±18 V risks permanent damage, and operation below ±6 V may cause reduced output swing and increased distortion.
Does TL072ACN require external compensation capacitors?
No - TL072ACN features internal frequency compensation optimized for unity-gain stability. Adding external compensation is unnecessary and may degrade bandwidth or phase margin. External capacitors should only be used for intentional filtering or noise reduction in specific application circuits.
Can TL072ACN drive low-impedance loads like 600 Ω audio lines?
TL072ACN is not optimized for direct 600 Ω driving: its output short-circuit current is 10–60 mA, limiting sustained output into such loads without clipping or thermal stress. For 600 Ω interfaces, use a dedicated line driver (e.g., BUF634) or add a discrete emitter-follower buffer stage.
How does TL072ACN differ from TL072CN?
TL072ACN specifies tighter input offset voltage (3–6 mV vs. 3–10 mV for TL072CN) and improved input offset drift (10 µV/°C max vs. unspecified for CN). Both share identical pinout, package, and core specifications, but the 'A' grade ensures higher DC precision for demanding analog signal chains.
