Integrator and Differentiator

Overview

The uA741 is a typical representative of the second generation of integrated operational amplifiers. It is a monolithic high-gain operational amplifier made using silicon epitaxial planar technology. Its features are: frequency compensation, short-circuit protection, offset voltage adjustment capability, high input differential and common-mode voltage range, no blocking phenomenon, low power consumption, and wide power supply voltage adaptability. It has a wide input common-mode voltage range and will not "block" during use. It does not require an external compensation capacitor when used in circuits such as integrators, summators, and general feedback amplifiers. The pins and functions of the μA741 are shown in the figure below:

(1) Integrator circuit, the integral of the output voltage and the input voltage is linearly related. The relationship between the output voltage and the input voltage is

(2) Differentiator, the differentiation of the output voltage and the input voltage is linearly related. The relationship between the output voltage and the input voltage is

3. Integrators are widely used in scanning circuits, A/D conversion, and analog operations.
4. Differentiators are widely used in waveform transformation and analog operations.
