A few years ago, Burr-Brown had a chip to do this, digital to 4-20mA, but when I went to use this in a design, the silicon was being turned. Since, I haven't looked at it again, so they may have dumped it because of noise issues. But take a look at ADI or Burr-Brown >From: personal >Reply-To: pic microcontroller discussion list >To: PICLIST@MITVMA.MIT.EDU >Subject: [EE]:how to output 4-20mA ana from PIC? >Date: Mon, 8 Jul 2002 22:52:57 -0400 > >normally how to do it? any IC available for >4-20 analog output? > > >BR, > >-- >http://www.piclist.com hint: The PICList is archived three different >ways.
