Product details
Overview
TL072CDT 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 (typ), 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 signal conditioning circuits.
For engineers reviewing the TL072CDT datasheet, TL072CDT pinout, TL072CDT application, or TL072CDT equivalent, key selection criteria include input bias current (≤200 pA), offset voltage drift (10 µV/°C), channel separation (120 dB), and SO8 thermal resistance (125 °C/W) for stability in temperature-varying analog front-ends.
Technical Context
The TL072CDT integrates matched high-voltage JFET and bipolar transistors on a single monolithic die, enabling high input impedance (>10¹² Ω) and latch-up-free operation. Its internal frequency compensation ensures unity-gain stability without external components.
Designed for general-purpose precision analog applications, it operates over 0–70 °C with supply voltages from ±3 V to ±18 V (6–36 V total), supporting dual-rail configurations and offering output short-circuit protection with infinite duration rating under thermal limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 16 V/µs typical - enables faithful reproduction of fast-slewing audio and control signals up to ~1 MHz without distortion |
| Input Voltage Noise | 15 nV/√Hz at 1 kHz - critical for low-level sensor amplification where noise floor dominates SNR |
| Input Bias Current | 200 pA max at +25 °C - preserves signal integrity in high-impedance source networks (e.g., piezoelectric sensors) |
| Common-Mode Range | ±11 V at ±15 V supply - allows direct interfacing with signals near supply rails without level-shifting |
| Channel Separation | 120 dB at 100 Hz - prevents crosstalk between dual channels in stereo or differential processing paths |
| Supply Current | 2.5 mA max per amplifier - supports dual-channel operation within 5 mA total, suitable for low-power analog subsystems |
Pinout & Package
TL072CDT uses an SO8 (Small Outline 8-pin) surface-mount package with standard JEDEC MS-012AC dimensions: 4.9 mm × 6.0 mm body, 1.27 mm pitch, and 1.75 mm height. Thermal resistance is 125 °C/W (junction-to-ambient).
| 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 | Differential input node for channel 1; high-impedance JFET gate with ≤200 pA bias current |
| 3 | Non-inverting Input 1 | Differential input node for channel 1; identical bias and impedance characteristics as Pin 2 |
| 4 | VCC− | Negative supply rail connection; must be referenced to system ground or negative rail in dual-supply systems |
| 5 | Non-inverting Input 2 | Independent input for second op-amp channel; electrically isolated with >120 dB channel separation |
| 6 | Inverting Input 2 | Second channel's inverting input; matches Pin 2 performance across temperature and supply variations |
| 7 | Output 2 | Second independent output; shares same AC/DC specs and drive capability as Pin 1 |
| 8 | VCC+ | Positive supply rail connection; supports up to +18 V in dual-supply or +36 V in single-supply configurations |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ≤200 pA enables stable DC coupling with megohm-level source impedances without significant offset error |
| High Common-Mode Rejection | 86 dB min ensures accurate differential signal extraction in noisy industrial environments |
| Internal Frequency Compensation | Guarantees unity-gain stability without external compensation capacitors - simplifies PCB layout |
| Output Short-Circuit Protection | Rated for indefinite short-circuit to either rail or ground, provided power dissipation stays within thermal limits |

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 |
|---|---|---|---|
| TL082CDR | Higher slew rate (13 V/µs vs. 16 V/µs), slightly higher input noise (18 nV/√Hz), same SO8 package | Marginally lower bandwidth fidelity in fast transient audio paths | Preferred where lower cost and broader distributor availability outweigh minor noise/speed trade-offs |
| RC4558DR | Bipolar input (vs. JFET), higher input bias current (300 nA), lower slew rate (1.7 V/µs), same pinout | Not suitable for high-impedance sources or wideband audio; limited to general-purpose DC/low-frequency use | Select only for legacy designs requiring drop-in replacement with relaxed noise and speed requirements |
Compared with TL072CDT, TL082CDR offers comparable noise and speed at lower cost but with marginally reduced phase margin; RC4558DR sacrifices JFET advantages entirely - making it viable only in cost-sensitive, low-bandwidth industrial controls where input impedance >1 MΩ is not required.

FAQ
What is the maximum supply voltage for TL072CDT?
The absolute maximum supply voltage is ±18 V (36 V total), but recommended operating range is ±3 V to ±18 V. Exceeding ±18 V risks permanent damage. At ±15 V supply, it delivers full specified performance including ±12 V output swing into 2 kΩ loads and 16 V/µs slew rate.
Does TL072CDT support single-supply operation?
Yes - TL072CDT operates from a single 6–36 V supply. For proper DC biasing, the input common-mode range extends to within 1.5 V of VCC−, so a mid-rail reference (e.g., VCC/2) is required for AC-coupled inputs or rail-to-rail output utilization in single-supply configurations.
How does TL072CDT compare to TL072IDT in terms of temperature range?
TL072CDT is rated for 0–70 °C ambient operation, while TL072IDT supports −40 to +125 °C. Electrical parameters like input offset drift (10 µV/°C) and supply current (2.5 mA max) are identical across both versions - only the guaranteed operating temperature envelope differs.
Is TL072CDT RoHS-compliant and lead-free?
Yes - TL072CDT is manufactured in ST's ECOPACK®-compliant SO8 package, meeting RoHS Directive 2011/65/EU and REACH regulations. The device is lead-free, halogen-free, and qualified for standard commercial reflow profiles per J-STD-020.
