opamp – Introduction to Operational Amplifier

Operational amplifier has two inputs, Inverting (-ve) and non inverting (+ve) inputs and one output. 741 is one of the traditional op-amp, which have 8 pins. two pins are inputs, one pin is output and a Vcc (+ve) and Vee (-ve), which are supply voltages (range 5 to 15 V). It also have two offset …

Operational amplifier and Opto-electronic devices

Operatinal amplifier Operatinal amplifier or OPAMP are basic element in an analogue¬† circuit. Opamp is a linear device. When signal is applied to minus terminal of opamp then output is in opposite phase of input. Differential gain of opamp should be greater than common mode gain. Ideal value of common mode rejection ratio CMMR is …
