LM386: Has LM386 been passed the latch-up test, JEDEC JESD78 with +/- 100mA?

 Hello Luis,

 Thank you very much for your prompt reply.

 Could I ask you an additional question as the follow?

 Q. I thought that all TI device has tested for latch-up as the following document even if the latch-up tolerance level may be lower than +/- 100mA.

      Latch-Up

      https://www.ti.com/lit/wp/scaa124/scaa124.pdf

     Was this device not tested for the latch-up tolerance?

     The customer has desided to use LM386 for their new products. So they want to get any tolerance performance for lach-up.

     Do you have any data for the device latch-up?

 Thank you again and best regards,

 Kazuya.

 Thank you very much for your depper resech.

 I'm looking forward to receiving your reply.

The customer needs the device latch up performance to judge whether it can be adopt to their product mass production without any problem or not.

 Thank you and best regards,

 Hello Luis,

 Did you get any data about LM386 latch up performance?

 The cusomer and I need the data strongly to use the device for mass production prodducts.

 Thank you and best regards,

 Kazuya.

Hello, Kazuya,

Sorry fo the delay on this. We are still working to get this information. Since it is an old device, we have some problems to collect this data. I will come back soon with the details about the information you are requesting.

Thank you for your patience.

Hello, Kazuya,

Unfortunately, we couldn't get this data since the device is too old and the support is very limited. We can only guarantee the data included in the datasheet.
