Product details
Overview
TL072BIDT 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 to ±15 V common-mode input range, and 2.5–4 MHz gain-bandwidth product - used in precision audio preamplifiers, active filters, and sensor signal conditioning circuits.
For engineers reviewing the TL072BIDT datasheet, TL072BIDT pinout, TL072BIDT application, or TL072BIDT equivalent, key selection criteria include input offset voltage (1–3 mV max at +25 °C), input bias current (≤200 pA), thermal stability (−40 °C to +125 °C operating range), and SO8 package compatibility with standard PCB layouts for dual op-amp designs.
Technical Context
The TL072BIDT integrates two matched high-voltage JFET input stages with bipolar output transistors on a single monolithic die, enabling rail-to-rail-compatible input operation up to ±15 V and differential input voltage tolerance of ±30 V. Its internal frequency compensation ensures unity-gain stability without external components.
Designed for low-distortion analog signal processing, it delivers 0.01 % THD at 1 kHz and 120 dB channel separation, supporting independent dual-amplifier configurations with minimal crosstalk - critical in stereo audio paths and multi-channel instrumentation front-ends.

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 | Wider input offset (3–10 mV), 0–70 °C temp range, lower cost | Consumer audio, non-critical industrial controls where extended temperature not required | Select when ambient stays within commercial range and offset budget allows ≥3 mV |
| OPA2134UA | Lower noise (8 nV/√Hz), higher GBP (8 MHz), ±18 V supply, no short-circuit protection | High-end audio DAC output stages requiring ultra-low distortion and wider bandwidth | Choose for premium audio where thermal fault resilience is secondary to noise performance |
Compared with TL072CDT, TL072BIDT offers tighter offset and extended temperature capability; versus OPA2134UA, it trades bandwidth and noise for built-in fault protection and broader supply tolerance - making it optimal for ruggedized industrial signal chains.

FAQ
What is the maximum supply voltage for TL072BIDT?
The absolute maximum supply voltage is ±18 V (36 V total), but recommended operating range is ±15 V for optimal performance. Exceeding ±18 V risks permanent damage. The device supports asymmetric supplies (e.g., +15 V/−5 V), provided total voltage remains ≤36 V and common-mode input limits are respected.
Does TL072BIDT require external compensation capacitors?
No - TL072BIDT features internal frequency compensation optimized for unity-gain stability. Adding external compensation is unnecessary and may degrade bandwidth or phase margin. It operates stably with gains ≥1 in inverting/non-inverting configurations without added components.
How does TL072BIDT compare to TL072AIDT in offset voltage?
TL072BIDT guarantees 1–3 mV input offset voltage at +25 °C, while TL072AIDT specifies 3–6 mV. Both share identical temperature drift (≤10 µV/°C) and noise performance. The "B" grade is selected where tighter initial DC accuracy is mandatory, such as in calibrated sensor front-ends.
Is TL072BIDT suitable for single-supply operation?
Yes - though optimized for split supplies, TL072BIDT supports single-supply operation (e.g., +12 V and GND) with proper input biasing. Its common-mode range extends to within 1.5 V of VCC−, allowing inputs down to −12 V in ±15 V mode or to GND in +12 V/0 V mode when biased correctly via resistor dividers.
