Thermometer circuit with AD595

Published:2012/9/16 21:24:00 Author:Ecco | Keyword: Thermometer circuit | From:SeekIC

the entire circuit is comprised of integrated circuits. This makes for some easy organization when it goes to the circuit board for soldering. In addition, I used only 3 of the pins on the 3rd nixie tube for the hundreds position in the display. Since I was only using three, I decided to save a 74141 IC and just use a few high voltage transistors (MPSA42). I figure the thermometer will very unlikely be in any situation where a temperature between 0 and 399 will ever need to be displayed, and if it is, the electronics will probably not work anyways.
