My experience with ADI's analog circuits

The real reason for using ADI was to develop single-phase electronic meters. At that time, ADE7755 was a chip strongly promoted by the power department, and domestic meter chips were not very good at that time.

It took a long time to adjust this chip, and after several board tests, it was finally adjusted to an accuracy of 0.1~0.3, which is a relatively good requirement.

Starting from this, I think ADI's analog circuits are indeed quite good. However, domestically produced meter chips are also very good now, and the price-performance ratio is good. Domestic analog circuits are also on the rise. I believe they are all good.

Later, I had the opportunity to use ADI7710 for multi-channel data acquisition and applied it to dams and bridges. It was also quite early. At that time, assembly language was still used. ADI7710 is still a pretty good chip. It is indeed better.

Later, I also paid much attention to some of ADI's products, including its ADUC84x series with AD conversion based on 51.

Of course, I have also used his isolation module 485 circuit and his IO isolation chip. Especially now that he has acquired Maxim, there are more options.

Very comprehensive, but domestic isolation chips are also starting to rise. If performance is considered first, of course you can consider ADI. If you also consider price and cost, you can comprehensively consider whether to use domestic or ADI or other brands.

In short, let's talk about the ADI chips we have used. Everyone has some impressions of this. Exchange and learn from each other!
