Overview
The TL072 is TI's dual JFET-input operational amplifier and remains the standard answer when a circuit needs high input impedance with low bias current. The matched JFET input pair draws only 65 pA typical and 200 pA maximum at 25 °C — roughly 7 nA maximum across the full 0 °C to 70 °C range — and presents about 1 TΩ of differential input resistance. That makes the TL072 the natural choice for charge amplifiers, piezo pickups, photodiode transimpedance stages, precision integrators and sample-and-hold circuits where a bipolar input would leak away the signal.
AC performance is far better than the classic LM358/LM324 generation: gain-bandwidth product is 3 MHz typical, slew rate 13 V/µs typical, and input voltage noise density 18 nV/√Hz at 1 kHz with 1.4 µVRMS in the 0.1 Hz to 10 Hz band. Quiescent current is 1.4 mA typical per amplifier (2.5 mA maximum), open-loop gain is 25 V/mV minimum and 200 V/mV typical, CMRR and PSRR are 100 dB typical, and the output swings to ±12 V minimum into 10 kΩ loads from ±15 V rails. A distinctive feature is the common-mode input range, which extends up to and includes VCC+ — the opposite of the LM324 — so the part can be used in high-side sensing configurations that include the positive rail.
TI offers the TL072C (0 °C to 70 °C), TL072I (−40 °C to +85 °C) and TL072M (−55 °C to +125 °C) temperature grades, plus the TL072A and TL072B offset grades at 6 mV and 3 mV maximum versus 10 mV for the base part. The newer TL072H is a re-spun die in the same pinout with 1 mV typical offset, 20 V/µs slew rate, 940 µA per channel and operation from ±2.25 V to ±20 V — a worthwhile upgrade for new designs. Note that, unlike the single TL071, the dual TL072 has no offset-null pins, so DC-critical designs must trim in firmware or with an external summing node.
Second sources include STMicroelectronics, onsemi, Nisshinbo/JRC and numerous Asian fabs, all pin-compatible in DIP-8, SOIC-8 and TSSOP-8. Pricing is stable and stock is deep; MOQ is 1 reel (2,500 pcs SOIC-8) or 100 pcs loose. Because the TL072 is popular in guitar pedals and DIY audio, remarked parts circulate on broker markets — check laser marking and verify input bias current on a sample, since clones often use bipolar die with nanoamp-level bias.

Procurement Tips
Buy the TL072ID (SOIC-8, −40 °C to +85 °C) rather than the TL072CP for any product that leaves the bench — the price difference is negligible and it removes a common field-failure excuse; ask for the grade and vendor to be printed on the BOM line.
Frequently Asked Questions
What is the difference between TL072, TL072A, TL072B and TL072H?
TL072, TL072A and TL072B are the same original die with progressively tighter input offset limits: 10 mV, 6 mV and 3 mV maximum respectively. The TL072H is a newer process with 1 mV typical offset, 20 V/µs slew rate, lower supply current and a wider ±2.25 V to ±20 V supply range while remaining pin-compatible.
When should I choose the TL072 over the NE5532?
Choose the TL072 when the source impedance is high (above about 10 kΩ) or when input bias current matters — its 65 pA JFET input produces negligible offset error, while the NE5532 draws 200 nA. Choose the NE5532 when the source is low impedance and voltage noise dominates: 5 nV/√Hz beats the TL072's 18 nV/√Hz, and it drives 600 Ω loads far better.
Can the TL072 run from a single supply?
Yes, down to a total of 4.5 V to 5 V with a mid-rail bias reference, although the datasheet specifies ±5 V to ±18 V dual supplies. Because the input range includes VCC+ but not VCC−, single-supply circuits need the signal biased a few volts above ground; the TLV2372 or LMV358 is usually simpler if the design must sense down to 0 V.
Why does my TL072 circuit oscillate or latch when the input goes below the negative rail?
JFET-input op-amps of this generation do not tolerate inputs driven below VCC−: the input stage can phase-reverse or latch until power is cycled. Keep the common-mode voltage inside the specified range, add series resistance and clamping diodes on external connectors, and consider a modern part with over-the-rail input capability if users can force the pin.
Is the TL072 still in production, or should I redesign?
TI lists the TL072 family as Active with a long-term product commitment, and the TL07xH generation extends the roadmap. For new designs that need lower offset and higher speed in the same socket, specify TL072H; for the widest second-source pool, the base TL072C/TL072ID remains the safest choice.
How do I detect counterfeit TL072 parts?
Measure input bias current — a genuine TL072 reads in the tens of picoamps with a simple charge-decay or feedback-resistor test, while remarked bipolar clones read in the nanoamps. Also check laser-etched marking, pin plating under magnification, and date-code consistency within a reel. We X-ray and electrically sample every lot we ship.
What is the MOQ and lead time?
MOQ 1 reel (2,500 pcs SOIC-8) or 100 pcs loose for prototypes; DIP-8 is available in tube quantities for hand-assembly lines. Shenzhen stock ships in 1-2 days, TI authorized channel replenishment takes 5-10 days for standard grades.
