What happens when the common terminal of V+ and V sources is not grounded?
What happens when the common terminal of V+ and V- sources is not grounded.
If the common point of the two supplies is not grounded, twice the supply voltage will get applied and it may damage the op-amp..
How is IC 741 tested?
Working of the circuit | Operational Amplifier 741 Tester Working of the circuit is simple and straight forward. The IC to be tested is configured in voltage comparator mode. Voltage at pin 3 (non inverting pin) is fixed where voltage at pin 2 (inverting pin) varying due to charging and discharging of capacitor C1.
What are the features of IC 741?
Features of 741 ICShort circuit and overload protection provided.In theory, the dc output voltage will be zero if both the inputs of the 741 IC are connected to the ground. … Low power consumption.Large common mode rejection ratio (CMRR) and differential voltage ranges.No external frequency compensation is required.More items…
Why We Use IC 741?
Amplifiers: 741 IC is mostly used to amplify signals of varying frequencies ranging from DC to higher radio frequencies. It is also used in frequency selective amplifiers which filter out signals of unwanted frequencies, E.g. tone control systems in stereo and Hi Fi systems.
What is the typical value of open loop gain for IC 741?
