Hi,
My customer is using LM3886 as shown attached file circuit.
This amp operation is good.
But he said that this device becomes too hot even if input voltage is 0V.
Customer wants to know whether this issue is for this circuit, or not.
Could you advice me about this circuit, please?
This device thermal resistance(theta JA) is 43 deg C.
and Figure12 in datasheet shows supply current at Vo=0 and Io=0.
I think that thermal desigen is important for this device.
and there is not problem in this circuit.
Best regards,
Shimizu
