Variable Gain Amplifier

49 in stock (can be backordered)

Description

The Variable Gain Amplifier is a non-inverting op-amp circuit that allows for a wide range of selectable gain values as well as a variable gain value with the use of a potentiomter. The kit demonstrates the principles of a non-inverting amplifier and the instructions include the explanation of the circuit as well as the formula that describes the gain of the circuit. An output buffer is provided to improve the output impedance of the Variable Gain Amplifier and the kit offers a maximum gain of up to 100. Please note that the LM358 has a maximum output voltage of VCC – 1.5V so if a 5V power supply is used for example then the maximum output voltage that you can achieve is 5 – 1.5 = 3.5V.
