Preamplifier Circuit Diagram. Here is simple op amp preamplifier circuit using lm382. The circuit is a simple two transistor pre amplifier using a feedback loop for enhancing the amplification.
Preamplifier circuit is used to meet one or more of the following requirements. This preamplifier circuit is built with an op amp ic of tl072 the noise is one of the main problems in high end audio systems. Here is simple op amp preamplifier circuit using lm382.
In the circuit it useslm382 low noise dual preamplifier and a few components so small circuit.
Below given is the circuit diagram for pre amplification of aux output of the mobile phone. This is a higher preamplifier circuit. Below given is the circuit diagram for pre amplification of aux output of the mobile phone. The low noise is one of the main characteristics of this circuit.
