Greetings dear forum members!
Today I was going through the specifications of an ASIC with a colleague, and I was shocked to hear that the manufacturer was only able to grant a 30% tolerance on the integrated resistors. Anything more accurate would have cost a whole lot more additional money. This ASIC however was created several years ago, and I was wondering how is the situation today?
Is it still normal to have such low accuracy for integrated resistors (without trimming and additional procedures) or did the industry develop since then?
I was trying to google this but no real relevant result came up. I guess it is only known by those who work with these things dayly, and I was hoping that I can find some of those people here .
Thank you in advance for answering my silly question!
