I have been using your company's LT1028MJ8 IC for 20 years now.After 20 years of using it, I am going to replace it with a new one, but it is not available in Korea.The one available in our country is LT1028CN8 IC, which is not compatible with the PCB I use because it has some different characteristics.So I want to know where I can get LT1028MJ8, or do you have a replacement?
The "M" package (8-lead ceramic DIP) is obsoleted per the datasheet page 2.
Analog Devices will no longer produce this device.
I understand that your company no longer produces "M" packages.I want to find a product that can replace the "M" package.Can you introduce me to your new replacement product?
What exactly about the LT1028CN8 characteristics you've noted is not compatible with the obsoleted LT1028MJ8?
From the image below, I see that the two packages (M on top, and N further below) are very close in dimensions:
Or are you referring to the temperature range of the "M" package (-55C to 125C)?
Please let me know more details of your needs, and I'll try and help.
