Hello E2E Experts,
Good day.
I was learning to test analog chips, taking LM386 N1 as the learning object. When I was referring to your schematic diagram, I found that the test conditions of electrical characteristics were too concise, so I could not use the information in the manual to restore the test conditions of the TI laboratory. I used the power supply, oscilloscope, signal generator, and other instruments in the laboratory. The results of the test are quite different from the manual. For example, I used the sweep method to test the bandwidth and the result was 210kHz, compared to the typical manual value of 300kHz. Therefore, I would like TI engineers to provide the test circuit diagram or detailed test method of the chip, including static current, input impedance, output power, bias current, and other electrical characteristics.
Regards,
