The voltage gain of this amplifier is 10 times. This gain is given by the relationship of values between the resistors, which can be changed. The power supply must be symmetrical with voltages from 6 to 12 V. The input impedance is 10 k ohms and the output impedance 50 ohms. Other equivalent operational amplifiers can be used. The maximum operating frequency is in the order of 100 kHz.
