What is the output impedance of a 741 op amp?
about 75 ohms
Op-amp Output Impedance For the 741 it is about 75 ohms but can be as high as several thousand ohms for some low power op-amps.
What is 741 op-amp IC?
The 741 Op-Amp or operational amplifier is a DC-coupled high gain differential amplifier with external negative feedback. It consists of 8 pins and It has only one op-amp inside. The main function of the 741 Op-Amp IC is to do the mathematical operations in various circuits.
What is offset null on a 741 op amp?
741 Op Amp Offset Null Offset null is a calibration feature of the op-amp. The op-amp is so sensitive to the input voltage that at times the output will generate a signal even when there is no intentional input. To avoid this condition for certain applications, offset null pins, pin 1 and pin 5 are provided.
