Product details
Overview
TL072CD from STMicroelectronics is a low-noise, JFET-input dual operational amplifier in SO8 package, featuring 16 V/µs slew rate, 15 nV/√Hz input voltage noise, and ±11 V common-mode input range at ±15 V supply. It delivers 0.01% THD at 1 kHz and supports rail-to-rail output swing up to ±12 V into 2 kΩ - widely used in audio preamplifiers, active filters, and sensor signal conditioning.
For engineers reviewing the TL072CD datasheet, TL072CD pinout, TL072CD application, or TL072CD equivalent, key selection criteria include JFET-input bias current (≤200 pA), low-noise performance for analog front-ends, dual-channel independence for stereo or differential architectures, and SO8 thermal resistance (125 °C/W) for industrial ambient operation.
Technical Context
The TL072CD uses a monolithic JFET-bipolar hybrid process to achieve high input impedance (>10¹² Ω) and low input bias current while maintaining fast large-signal response. Its internal frequency compensation ensures unity-gain stability without external components.
It operates over 0 to +70 °C with supply voltage range of ±3 V to ±18 V (or 6–36 V total), and features latch-up free design, output short-circuit protection, and 120 dB channel separation - critical for dual-amplifier isolation in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 16 V/µs typical - enables clean 100 kHz sine wave amplification without slew-induced distortion |
| Input Voltage Noise | 15 nV/√Hz at 1 kHz - suitable for low-level microphone or piezoelectric sensor amplification |
| Input Bias Current | 20 pA typical at +25 °C - minimizes DC error in high-impedance transducer interfaces |
| Common-Mode Range | ±11 V at ±15 V supply - supports inputs near negative rail, enabling single-supply-compatible configurations |
| THD + N | 0.01% at 1 kHz, 2 Vpp - meets fidelity requirements for line-level audio signal paths |
| Supply Current | 1.4 mA per amplifier - allows dual op-amp use in power-constrained instrumentation |
| Gain-Bandwidth Product | 3 MHz typical - supports stable closed-loop gain up to ~30 at 100 kHz |
Pinout & Package
TL072CD is housed in an 8-pin SO8 (Small Outline) surface-mount package with standard JEDEC MS-012AC dimensions (5.0 × 4.0 × 1.75 mm), RoHS-compliant and ECOPACK® certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output 1 | Amplified output of first op-amp channel; capable of ±12 V swing into 2 kΩ load |
| 2 | Inverting Input 1 | High-impedance JFET node; bias current ≤200 pA enables precision inverting configurations |
| 3 | Non-inverting Input 1 | Matched to Pin 2; supports unity-gain buffer or high-Z sensor interface |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally to minimize noise coupling |
| 5 | Non-inverting Input 2 | Independent second channel input; 120 dB channel separation prevents crosstalk in dual-path designs |
| 6 | Inverting Input 2 | Second channel inverting node; identical electrical specs to Pin 2 |
| 7 | Output 2 | Second independent output; fully isolated from Output 1 except via shared supply rails |
| 8 | VCC+ | Positive supply rail; requires local 100 nF ceramic decoupling for stability |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise JFET input stage | 15 nV/√Hz input voltage noise enables high-fidelity analog signal amplification without added noise floor |
| High slew rate | 16 V/µs supports wideband applications such as active bandpass filters up to 100 kHz |
| Output short-circuit protection | Withstands indefinite short to either rail or ground - improves system robustness in test fixtures and field service |
| Internal frequency compensation | Guarantees stability at unity gain without external compensation components, reducing BOM count |
| Latch-up free operation | Immune to CMOS-style latch-up under overvoltage or ESD stress - enhances reliability in noisy industrial environments |
Applications

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 |
|---|---|---|---|
| TL082CD | Higher input noise (18 nV/√Hz), slightly faster slew rate (13 V/µs), same pinout and supply range | Less suitable for ultra-low-noise mic preamps but acceptable for general-purpose filtering | Prefer TL072CD where noise floor is critical; TL082CD offers marginally better speed at cost of SNR |
| RC4558CD | Bipolar input (higher Ib = 500 nA), lower slew rate (1.7 V/µs), no JFET noise advantage | Used in cost-sensitive consumer audio where THD < 0.02% suffices and input impedance >1 MΩ is not required | Choose TL072CD when high Zin, low Ib, or low noise are mandatory; RC4558CD only for legacy cost-driven replacements |
Compared with TL082CD and RC4558CD, TL072CD uniquely balances low noise, high input impedance, and industrial temperature tolerance - making it optimal for precision analog signal chains where fidelity and DC accuracy coexist.

FAQ
What is the maximum operating supply voltage for TL072CD?
The TL072CD supports a total supply voltage range of 6 V to 36 V (±3 V to ±18 V). Absolute maximum ratings specify ±18 V, but sustained operation above ±15 V requires derating due to thermal limits - especially in SO8 packages with 125 °C/W junction-to-ambient resistance. Data sheet Table 2 confirms 0–70 °C operation at full ±18 V.
Does TL072CD support single-supply operation?
Yes - TL072CD can operate from a single supply (e.g., +12 V and GND) by biasing inputs and outputs within its common-mode and output swing limits. Its common-mode range extends to VCC− + 1.5 V and VCC+ − 1.5 V, and output swings to within ~1.5 V of each rail. External DC biasing (e.g., mid-rail reference) is required for AC-coupled signals.
How does TL072CD differ from TL072IDT?
TL072CDT (and TL072CD) is rated for 0 to +70 °C operation, while TL072IDT is specified for −40 to +125 °C. Electrical parameters like input offset drift (10 µV/°C) and supply current variation are guaranteed across their respective temperature ranges. Both share identical SO8 packaging, pinout, and room-temperature specs - only thermal qualification differs.
Is TL072CD pin-compatible with other dual op-amps like LM358?
No - TL072CD uses standard SO8 dual op-amp pinout (Pin 1 = Out1, Pin 2 = In−1, Pin 3 = In+1, Pin 4 = V−, Pin 5 = In+2, Pin 6 = In−2, Pin 7 = Out2, Pin 8 = V+), which matches TL082, NE5532, and RC4558. LM358 uses different pinout (Pin 1 = Out1, Pin 2 = In−1, Pin 3 = In+1, Pin 4 = V−, Pin 5 = In+2, Pin 6 = In−2, Pin 7 = Out2, Pin 8 = V+), so physical pin mapping aligns but electrical behavior (bipolar vs. JFET input) and specs differ significantly.
