LM386: Quick question: yes or no

Lakhal Mohammed

Part Number: LM386

Hello,

Does LM368 require an initial calibration or does it have a procedure to follow for the first measurement? or is it ready to be used for the first time?

Thank you

Hi, Lakhal,

The LM386 does not require an initial calibration. I would just recommend to ensure that the Bypass pin have the 10uF capacitor as close as possible to the pin and Vs is completely stable and there's no ripple when using the device. This device is sensitive to voltage changes on these pins.

Please let me know if you have additional questions or comments.

Best regards,

Hi, Lakhal,

I apologize for my late response. For some reason I didn't get the notification of your answer.

The schematic seems to be all in order. I didn't find anything that should be modified.

Best regards,
