Product details
Overview
TL072IDT 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), ±12 V common-mode input range at ±15 V supply, and 2.5 mA quiescent current per amplifier. It is used in audio preamplifiers, active filters, and sensor signal conditioning where high input impedance and low distortion are critical.
For engineers reviewing the TL072IDT datasheet, TL072IDT pinout, TL072IDT application, or TL072IDT equivalent, this page delivers verified electrical parameters, validated SO8 pin mapping, real-world use cases in precision analog circuits, and confirmed alternative op-amps with documented functional trade-offs.
Technical Context
The TL072IDT integrates two matched JFET-input op-amp channels on a single monolithic die, enabling dual-channel operation without crosstalk degradation beyond 120 dB channel separation. Its internal frequency compensation ensures unity-gain stability across temperature and load conditions.
Designed for industrial-grade operation, it supports −40 °C to +125 °C ambient range with ±18 V absolute maximum supply, ±15 V input voltage limit, and latch-up free behavior under transient overvoltage conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 16 V/µs typical - enables clean 100 kHz sine wave amplification at ±10 V output swing |
| Input Voltage Noise | 15 nV/√Hz at 1 kHz - suitable for low-level microphone and piezoelectric sensor interfaces |
| Input Bias Current | 20 pA typical at 25 °C - preserves signal integrity in high-impedance transducer networks |
| Common-Mode Range | ±11 V at ±15 V supply - allows rail-to-rail input operation within 4 V of either supply rail |
| Supply Current | 2.5 mA per amplifier max - supports dual-channel analog front-ends with <5 mA total quiescent draw |
| THD | 0.01 % typical at 1 kHz - meets fidelity requirements for professional audio line drivers |
| Gain-Bandwidth Product | 4 MHz typical - supports stable closed-loop gain ≥10 up to 400 kHz |
Pinout & Package
TL072IDT is housed in an 8-pin SO8 (Small Outline) plastic surface-mount package with standard JEDEC MS-012AC dimensions (5.0 × 6.2 mm body, 1.27 mm pitch). Thermal resistance is 125 °C/W junction-to-ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output 1 | Amplified output node for first op-amp channel; capable of ±12 V swing into 2 kΩ load |
| 2 | Inverting Input 1 | Negative feedback terminal for channel 1; high-impedance JFET input (10¹² Ω) |
| 3 | Non-inverting Input 1 | Positive input for channel 1; accepts signals within ±11 V common-mode range |
| 4 | VCC− | Negative supply rail connection; must be referenced to system ground midpoint in split-supply designs |
| 5 | Non-inverting Input 2 | Positive input for second op-amp channel; electrically isolated but thermally coupled to channel 1 |
| 6 | Inverting Input 2 | Negative feedback terminal for channel 2; identical bias and noise performance to pin 2 |
| 7 | Output 2 | Second independent output; supports simultaneous dual-channel signal processing |
| 8 | VCC+ | Positive supply rail; supplies both amplifiers; requires local 100 nF decoupling |
Key Features

Use Value: High slew rate (16 V/µs) and 10¹² Ω input impedance prevent settling delay and loading errors in isolated loop circuits. |
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 |
|---|---|---|---|
| TL072CDT | Commercial temperature range (0 °C to +70 °C); same electrical specs except wider input offset voltage (3–10 mV vs. 1–3 mV for TL072B grade) | Restricted to non-industrial environments; unsuitable for extended ambient or automotive under-hood use | Select when cost sensitivity outweighs temperature robustness and long-term drift stability |
| OPA2134PA | Lower input voltage noise (8 nV/√Hz), higher GBP (8 MHz), but higher supply current (4 mA per amp) and no internal short-circuit protection | Better suited for ultra-low-noise audio mastering; less tolerant of output faults or capacitive loading | Choose for premium audio fidelity where thermal headroom and fault resilience are secondary |
Compared with TL072CDT and OPA2134PA, TL072IDT uniquely balances industrial temperature range (−40 °C to +125 °C), integrated short-circuit protection, and low-noise JFET input-making it optimal for ruggedized analog signal chains requiring reliability without premium cost.

FAQ
What is the maximum operating junction temperature for TL072IDT?
The TL072IDT has a maximum junction temperature of +150 °C, supported by its −40 °C to +125 °C ambient operating range and 125 °C/W junction-to-ambient thermal resistance in SO8 package. Derating is required above +70 °C ambient to maintain safe junction temperatures under full load.
Does TL072IDT support single-supply operation?
Yes - TL072IDT operates with single supplies from 6 V to 36 V (e.g., +12 V and GND), provided input common-mode and output swing remain within specified limits. The input common-mode range extends to within 4 V of either rail, and output swing reaches within 2 V of each rail under 10 kΩ load.
How does TL072IDT differ from TL072IYDT?
TL072IYDT is the AEC-Q100 qualified automotive variant with enhanced screening (AEC-Q001/Q002), while TL072IDT is industrial-grade with identical electrical specs and SO8 packaging but without automotive qualification documentation or extended reliability testing. Both share −40 °C to +125 °C rating.
Can TL072IDT drive capacitive loads directly?
TL072IDT is not optimized for direct capacitive loads >100 pF without external compensation. Driving cables or ADC input capacitance may cause peaking or oscillation; a series resistor (e.g., 100 Ω) between output and load is recommended to ensure stability per Figure 14 in the datasheet.
