Lm741 pinout download free7/5/2023 With this type of supply, the output will go high: to 9V and Low” to -9V. The 741 op-amp uses a split power supply.Įxample +9V on pin7 and -9V on pin 4. If not, we will explain how the output changes according to the voltage on the inputs. If the +input into the same negative value, the output will become zero (volts).ĭo you understand? It’s okay if you are still confused.ĭid you fully understand the answers to the 4 examples on the previous?.And, the -input is negative the output will go minus.If the -input into the same positive value, the output will fall to zero.As the voltage on the +input increase, the output goes high.If the difference between the two input voltage is zero, too. It is according to the voltage on the two inputs. The following graph shows how the output voltage changes. Because the sensing range for the op-amp is only about 100 micro-volts. This makes them very sensitive & ideal as error sensors. We can couple the op-amp directly and has a very high gain(typically 100,000). Differential amplifier-I often see in the power supply circuit as an error sensor.Non-inverting amplifier-the input (-) connected to GND. ![]()
