The TL082IP is a single operational amplifier (op-amp) integrated circuit with high-performance features. It is a general-purpose op-amp suitable for use in many applications requiring low-cost, low-noise performance. This op-amp includes two independent, high-gain, internally frequency compensated op-amps. The TL082IP is ideal for use in audio or instrumentation amplifiers, active filters, DC to DC conversion circuits, comparators, operational buffers, and other functions. It is also suitable for active filtering, range switching, and signal processing applications.

Application Fields

The TL082IP is a versatile op-amp with many application fields such as low- frequency amplifier, single amplifier, instrumentation amplifier, precision rectifier and active filter. Each part of the op-amp has their own application fields. For example, the two op-amps are widely used in audio or instrumentation amplifiers, active filters and DC to DC conversion circuits. The summing function of op-amp is mainly used to construct microphone preamplifier, low-frequency filter, and tone filter. The difference function of op-amp is mainly applied to make active filter, notch filter, and other signal processing applications. Other application fields of op-amp include non-inverting amplifier, comparator, and sum & difference amplifier. The benefit of using this op-amp includes its low cost and low-noise performance.

Working Principle

The TL082IP is a general-purpose dual op-amp that consists of two independent circuits. Each circuit has three terminals, an input terminal (non-inverting input (non-inverting input) and inverting input (inverting input)), and output terminal. The input terminal is where the signal is applied, and the output terminal is where the amplified or converted signal is output. The input and output terminals are connected to each other via two feedback resistors. The two resistors form a voltage divider coupled between the input and output of the op-amp.

The input signal is usually applied to the non-inverting input terminal while the inverting input terminal acts as the feedback. The two resistors also form a variable potential divider circuit. When the input and output signals are not equal, a difference voltage is generated, which is amplified by the op-amp. The amplified signal is then fed back to the inverting direction and the closed loop gain of the op-amp is determined by the ratio of the two feedback resistors. The output signal is the sum or difference of the input and feedback signals multiplied by the open-loop gain of the op-amp.

The TL083IP includes two internal voltage reference. The output of the op-amp is referenced to the voltage divider coupled between the two voltage references. This prevents the output from exceeding the maximum voltage level of the op-amp, while at the same time providing a stable output. The adjustable offset, DC bias and AC coupling are also possible by changing the value of the two resistors.

Conclusion

The TL082IP is a general-purpose, single operational amplifier integrated circuit with high-performance features. The two independent, high-gain, internally frequency-compensated op-amps make it ideal for use in audio or instrumentation amplifiers, active filters, DC to DC conversion circuits, comparators, operational buffers and other applications. It includes two internal voltage references, which prevents the output from exceeding the maximum voltage level of the op-amp and provides a stable output.
