To be fair, I _did_ include "ADC" in the text. I completely agree with your frustration with popups; the web isn't nearly as friendly as it used to be. I've had some issues with Analog/Linear/Maxim datasheet links breaking because of all the acquisitions and mergers. I thought it best to link to the ... (more) |

I added direct links to the datasheets. We can probably ignore the AD74413R, which is a DAC that's sourcing 4-20 mA for the control loop. The feedback loop is driven by 5V (left side of schematic 1) through the 200 Ω and out `PREG_N` where the pressure regulator sinks it. On the other side, `IIN1_DP`... (more) |

The link is the official Analog product page. I opened it in a new browser session and the pop-up is one of those annoying "cookies settings" BS things that all the web sites are doing these days. Suffice to say, for the purposes of this question, the IC isn't that important, I probably should have e... (more) |

I definitely could have been more clear. You've answered my main question by explaining that current mirrors are a subcategory of current-controlled current sources. All the detail about the pressure regulator was my not-so-great attempt to provide context, but I think it muddied the waters a bit. I ... (more) |
