There we go again.

Someone wants support on ADC0804 as he wants to use it. And there is a suggestion to use 7135. Nothing wrong per se.

But an alternate hardware solution is in order if the used one is inadequate; obsolete; or outright a wrong choice. In this case none of these apply.

Most times such tangential references divert the focus off the primary thread.

OK these are purely my views and there is no need for anyone to subscribe to it. Just mentioning it as I feel about it.
