TDA7377 Circuit Diagram
This is a [2x30w] = 60Watts Amplifier based on IC TDA7377 circuit diagram. The Integrated Circuit (IC) TDA7377 Application is a DUAL/QUAD Power Amplifier, it has four inputs pin [4,5 - 11,12 pin] and outputs channels [1,2 - 14,15] which each channel as 15W peak power output. In this Project, this Circuit Diagram is a stereo amplifier, [4x15w = 60W] peak RMS, It we be 15w 4ohms for each 4 speakers, I already connect the “standby” contact to the positive potential using 10k resistor to activate the amplifier.
Additionally, this IC is already amplifying IC which requires just few external components for its operation. And the main amplifying components are already inbuilt. As a result of this, it is simple and convenient for even a learner to build an audio amplifier using the TDA7377 IC. Before you Assembled this circuit in vero broad, TDA7377 should be mounted on a heat sink for cooling the IC and it help in cooling the IC while operating. Let get started use the circuit diagram below to build it
