Note − IC 741 op-amp is the most popular and practical op-amp. The operating Bandwidth should be as high as possible. Output offset voltage should be as low as possible. Mathematically, the open loop voltage gain of an op-amp is represented as − ![]() The open loop voltage gain of an op-amp is its differential gain without any feedback path. This section discusses these characteristics in detail as given below − Open loop voltage gain The important characteristics or parameters of an operational amplifier are as follows − The terminals are named based on the phase relationship between their respective inputs and outputs. One of those terminals is called as the inverting terminal and the other one is called as the non-inverting terminal. A differential amplifier is present at the input stage of an op-amp and hence an op-amp consists of two input terminals. An operational amplifier (op-amp) is a DC-coupled high-gain electronic voltage amplifier Direct- coupled high gain amplifier usually consisting of one or more differential amplifiers Output stage is generally a push-pull or push-pull complementary-symmetry pair. Construction of Operational AmplifierĪn op-amp consists of differential amplifier(s), a level translator and an output stage. This chapter discusses the characteristics and types of op-amps. You can operate op-amp both with AC and DC signals. ![]() ![]() An op-amp is a direct coupled high gain amplifier. Operational Amplifier, also called as an Op-Amp, is an integrated circuit, which can be used to perform various linear, non-linear, and mathematical operations.
