Inverting amplifiers Non-inverting amplifiers Di erential amplifiers Summing amplifiers Integrator Schmitt trigger Voltage followers Analog to Digital converter Digital to Analog converter Filter circuits Instrumentation amplifiers Oscillator circuits What is called input o set voltage of an Op-amp? The input o set voltage is defined as the voltage that must be applied between the two input terminals to balance the Op-amp or to obtain a null or zero volts at the output. What is called output o set voltage of an Op-amp? The output o set voltage is the DC voltage present at the output of the op-amp when the two input terminals are grounded or shorted.

Operational Amplifier Viva Interview Questions and Answers
Define CMRR. Common Mode Rejection Ratio (CMRR) of a di erential amplifier is the ratio of the common-mode gain to di erential-mode gain. It is the ability of the amplifier to reject common-mode signals. Define PSRR. Power Supply Rejection Ratio (PSRR) is the ratio of the change in supply voltage to the corresponding change in the output voltage it produces. It is the capability of the circuit to suppress any power supply variations to its output signal. Define the slew rate. SPONSORED SEARCHES

Slew rate is defined as the maximum rate of change of output voltage or current by a step input per unit of time. It is expressed as a V /µs, that it the output voltage rises or falls with respect to a unit time. What are practical op-amp parameters? Finite input impedance Output impedance is not zero Finite Bandwidth Output saturation voltage Input o set voltage is present Output o set voltage is present Finite CMRR Finite PSRR A ected by Noise Cause Temperature dri List few op-amp IC’s. IC 741 – It is the most commonly used op-amp IC comes with 8-pin dual-in-line package. IC LM324, LM224, LM2902 are a series of IC’s with quad operational amplifiers. LM709, LM101, etc… are di erent general purpose operational amplifiers used for industrial purposes. https://mechatrofice.com/circuits/op-amp-viva-interview-questions-answers
