DIY Electronic dot com would like to present with you about 200 watts audio amplifier circuit project including schematic ,PCB ,component layout and wring.
You can take this circuit to apply with your audio devices .
About sound quality,We think,the sound well in B class as with lowest noise,bass lower. Basicly circuit functional ,We take the MOSFET with ECX10N16 and ECX10P16.
Which ECX10N16 is control and amplify in positive voltage and ECX10P16 is control and amplify in negative voltage.
Performance of the the amplifier
Output power (RMS ) 140W into 8 ohms, 200W into 4 ohms
Frequency Response: 20Hz – 80kHz-1dB points
Input sensitivity: 830mV for 200W into 4 ohms
Distortion: <0.1% (20 Hz – 20 kHz)
Signal-to-Noise Ratio:. > 102dB unweighted,
105dB A-weighted with respect to 200W into 4 ohms.
Picture below is PCB component side and wring with devices.
Could you copy PCB and all positions of components.
So,We have all board wring and interfacing,How to connect each board.
