Op Amps can be chained together to increase the overall gain of an amplifier, this is called cascading

Due to the input and output impedances of op amps, there is no loading effect.

Each amplifier is then called a 'stage'.

Stage I
Stage 2
Stage 3
= A2V2
VI
= A3V3

Note: The range of input voltages must be small enough to avoid saturation when amplified
