Input Impedance Of Op Amp Lm741 Is. Output voltage gain input voltage. The o p of the 741 ic op amp is below 100 ohms.
Output voltage gain input voltage. The op amp ic 741 is a dc coupled high gain differential amplifier with external negative feedback. One common configuration is in a non inverting amplifier configuration.
It is this circuit that is used when requiring very high levels of input impedance.
The input impedance of the ic 741 op amp is above 100kilo ohms. Here is simple op amp preamplifier circuit using lm382. Ic 741 is characterized by the almost infinite open loop gain 100 000 almost infinite input impedance 2mω and almost zero output impedance 75ω. The lm741 can operate with a single or dual power supply voltage.
