The Semtech Corporation\'s TL082IDRE4 is an advanced low-power dual operational amplifier that is designed for high performance, low-cost, and general-purpose applications. It is designed with a wide range of features that provide designers with the flexibility needed to quickly and efficiently integrate the amplifier into any system. The TL082IDRE4 operational amplifier can be used for a variety of purposes, from low-noise high-impedance buffering and gain control, to high-speed data acquisition circuitry. Its low power and excellent temperature stability make it an ideal component for a wide variety of linear applications.

Application Field

The TL082IDRE4 is a highly versatile dual-channel operational amplifier that can be used in a wide variety of analog circuit applications. It is suitable for use in precision-gain stages, power stages, instrumentation amplifiers, active filters, and single-supply amplifiers. The device is also well-suited for use as a power audio amplifier, as its low distortion, low bias currents, and low power consumption make it ideal for low-power audio amplifiers. The TL082IDRE4 can also be used for AC or DC coupled signal amplification and summer functions. The device has a wide common-mode input range and excellent common-mode and power supply rejection ratios. Its low input bias current prevents error signals from drifting even when it is placed in a noisy environment. The TL082IDRE4 also offers excellent temperature stability and can withstand high temperature exposure.

Working Principle

The TL082IDRE4 operates by amplifying the difference between its two inputs. The input signals must be applied to the non-inverting (+) and inverting (-) inputs, respectively. The inverting input receives an inverted version of the input signal, and the output is the amplified version of this difference. The TL082IDRE4 has a relatively high gain-bandwidth product (GBW), typically 4MHz, with a slew rate of 12V/µs. The high GBW allows the amplifier to process high-frequency signals without much distortion. The amplifier also offers excellent common-mode rejection, meaning that noise signals in the environment are not amplified. The amplifier also provides high output current drive with a current capability of 100mA.

The TL082IDRE4 is a power-efficient dual-channel amplifier. Its maximum power supply voltage is ±18V for both channels, providing a high level of voltage headroom. The power supply rejection ratio of 76dB eliminates power supply noise from the amplifier\'s output. Its 700µA quiescent current also contributes to its low power consumption.

Conclusion

The TL082IDRE4 is an excellent dual-channel operational amplifier for a wide range of linear applications, such as precision-gain stages, power stages, instrumentation amplifiers, active filters, single-supply amplifiers, and audio amplifiers. It has a wide gain-bandwidth product (GBW) and high output current drive, as well as excellent common-mode rejection and low power consumption. The low input bias current also makes the TL082IDRE4 an ideal component for low-noise high-impedance buffering and gain control. The TL082IDRE4 is sure to be an invaluable component in any design.
