Key Features
- Dual JFET-input op-amp with 0.2 nA input bias current at 25°C, enabling low-error interfacing to high-impedance transducers and sensor networks
- 3 MHz gain-bandwidth product with low input noise voltage for audio preamplifier, active filter, and wideband signal processing applications
- 70 dB minimum CMRR and ±15 V supply rail compatibility ensuring reliable differential signal rejection across a broad range of analog front-end circuits
- 8-pin DIP (TL072CN) package for easy breadboard prototyping and through-hole PCB assembly in studio and industrial equipment
Applications
The TL072CN is widely used in audio preamplifiers, guitar effects pedals, and mixing console channel strips where its low noise JFET inputs and 3 MHz bandwidth deliver clean signal amplification across the 20 Hz to 20 kHz audio band. Its dual-channel configuration supports stereo or fully-differential signal paths in a single 8-pin DIP package, reducing component count in portable and rack-mounted audio equipment. The device also finds use in active crossover networks, phono equalizer stages, and precision integrators in industrial instrumentation requiring low bias-current input stages.

Frequently Asked Questions
How does the TL072CN's 3 MHz gain-bandwidth product compare to NE5532 for audio preamplifier designs at gain-of-100?
At a closed-loop gain of 100 (40 dB), the TL072CN provides a -3 dB bandwidth of approximately 30 kHz, which comfortably covers the 20 Hz to 20 kHz audio band. The NE5532 offers a higher 10 MHz GBW, yielding 100 kHz bandwidth at the same gain, making it preferable for RF or ultrasonic preamps. For standard audio, the TL072CN's JFET inputs give it a significant advantage in input impedance, exceeding 10^12 Ω, versus the NE5532's bipolar inputs at roughly 300 kΩ.
What maximum input offset voltage does the TL072CN specify and how should designers compensate it in a precision DC amplifier?
The TL072CN specifies a maximum input offset voltage of 13000 µV (13 mV) at 25°C, which is relatively high for precision DC applications. At a gain of 10, this offset introduces up to 130 mV of output error. Designers can use the TL072AC or TL071 single-channel variant with 3000 µV max offset, or add an external offset-null potentiometer using the offset-adjust pins, or implement an auto-zero correction loop in firmware-driven ADC systems.
For a stereo guitar effects pedal running on a 9 V single supply, does the TL072CN operate correctly?
The TL072CN operates from ±5 V to ±15 V dual supplies. On a 9 V single supply it can work by biasing the non-inverting inputs at 4.5 V (V+/2), giving a ±4.5 V effective swing. Output clipping occurs approximately 1 V to 2 V from each rail, yielding a usable swing of roughly 5 V peak-to-peak at 9 V. This is adequate for instrument-level signals below 1 V RMS, making the TL072CN a popular choice in boutique pedal designs when a bipolar supply is unavailable.
How many TL072CN units are needed to build a 4-pole Butterworth low-pass filter and what is the component count compared to using LF347?
A 4-pole Butterworth filter requires 2 second-order Sallen-Key stages, consuming all 2 amplifier channels in a single TL072CN (8-pin DIP). If the signal chain also needs a buffer or gain stage, a second TL072CN is required, using 4 ICs total for an 8-channel system. The LF347 quad op-amp consolidates 4 channels in one 14-pin DIP, halving the IC count and associated bypass capacitors, which reduces BOM by roughly 50% for multi-pole filter banks.
