TL072 Pinout: Specifications, Applications, and Maintenance

An integrated circuit (IC) or microchip is a tiny electronic device that performs specific functions. The TL072 is a low-power CMOS op-amp integrated circuit. It is very common, especially for audio applications. This article explains what the TL072 pinout is and why it matters. Let’s get started!

What is TL072?

The TL072 is a dual operational amplifier with a fast slew rate and high-speed J–FET input that also comes in reduced noise versions. The input bias and offset currents are also both small. Because it is a dual Op-amp IC, there are two op-amps within. Because of its low harmonic distortion and noise, the TL07x series is the best choice for high-precision applications. Also, the pre-amplification stage of audio uses the TL072.

Technical Specifications and Functions of TL072 

 

TL072 Functions

 

  • It has low power consumption, input-bias currents, and Offset currents
  • Supplied with the short circuit protection
  • Operation of IC is Latch-up free
  • It has a dual op-amp IC.
  • Its input impedance is excessive
  • Inner Frequency Compensation
  • Extensive common-mode (as much as VCC+) and differential voltage variety  

 

Technical Specification

 

  • Distortion of Harmonic is low (generally 0.003%)
  • Low noise at the operation Vn = 18 nV/√Hz (common) at f = 1 kHz
  • Having a high slew charge (commonly 13 V/μs)
  • Supply voltage: 6 - 36v
  • Having countless output short circuit duration
  • Garage temperature:  -65 °C - 150 °C
  • Operating Temperature:  -4°C - 125 °C
  • Output current: 10mA (commonly)

 

Where Should You Use IC TL072?

 

Audio pre-amplification mostly uses the TL072 that requires great accuracy on low harmonic and noise. Pre-amplification is a technique for obtaining output audio with little noise, interference, and distortion. To regulate volume, bass, and treble, the IC TL072 works in the same manner as other op-amp ICs and compares the voltage. It is a voltage comparator IC.

How Should You Use IC TL072?

 

To increase sound quality, the TL072 comes in handy as it is a low-cost, very accurate audio pre-amplification device. After connecting the audio input to the output, the output will have little noise and distortion. We can increase the value of the resistor because the input impedance is large.

Impedance balance, which reduces distortion, is the responsibility of one of the resistors. Negative feedback resistors are used to assess the output signal. The noise will increase if the negative resistor setting is too high, while the noise will drop if the setting is too low, although distortion may increase as the load on the IC rises.

 

Applications

 

  • UPS
  • Solar applications
  • Inverters
  • Motor drives
  • Oscilloscopes
  • Audio equipment

Substitute, Identical, or Replacement ICs and Part Numbers

 

The analogous ICs we are mentioning here will not always be a comparable replacement for the TL072, but in certain instances, they will function well, and in others, they will not. Therefore, testing is necessary to determine which equivalent IC is effective. The equivalent ICs are the TL1971, LM358, and Ne5532. Nonetheless, if TL072 is unavailable, this IC's single and quad variants can function identically to TL072.
