2 Largesignal voltage gain This is what we have been calling

(2) Large-signal voltage gain: This is what we have been calling the open-loop voltage gain. It is the gain of the opamp. This is the number we assume to be infinite when making the ideal opamp assumption, so you would expect the specified number to be fairly large

Assuming we are using the opamp at an ambient temperature of 25°C, with ±15V supplies, and a load of at least 2K, what is the typical large-signal voltage gain of an LM741 opamp? Look carefully at the units!

(3)Output voltage swing: This specification describes the voltage range that the opamp can output without saturating. In lecture we have said that the opamp output is limited to a range somewhat smaller than ±Vsupply. This specification tells us what that range is.

Assuming we are using ±15V power supplies and are driving a load of greater than 10K, what are the typical and worst-case output voltage ranges for the LM741?

Solution

large signal voltage gain of of an LM741 opamp is infinite.

But in real world infinitre means the gain is 10^6
