LM386: Electrical performance test of LM386

Part Number: LM386

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.
