0-5 V signal
0-5 V signal
(OP)
Hi,
I'm trying to build a box that will simulate 0-5V signal.I'm using this signal as a remote temperature set point for a heat exchanger. I have already tried it using DC power supply and potentiometer in series and it works. Now I'm wondering if there is a driver chip that will do same?Thanks

thanks for replaying to this question. I have already used 7805 to step down voltage from my regulated DC power supply (+-15 V)to 5V and potentiometer in series to change output voltage.I can control temperature by adjusting potentiometer( I believe 40 mV is one C).I'm trying to find some IC's that will do same thing( adjustable 0-5V output). I'm thinking about using buffer op amps.
Thanks.

If you want to produce a computer interface you need to think about the set point control range you want, and how many bits resolution this equals. The simplest starting point is an 8-bit digital to analog converter chip - the well-, inexpensive DAC08 (or variants) - which should give you about 20mV per bit resolution, over a 0-5V total range.

Sorry for the confusion guys. Let me start all over. I'm building a box that will help me diagnose if my heat exchanger ( here heat exchanger beeing a support equipment for some other tool) communicates with the main tool, before I install it. I'm trying to build a box that will send voltage signal (from 0 to 5 V, temperature range 0-200 C) that is going to simulate main tool and to see if heat exchanger is going to take it. I have already made it to work with before mentioned set up and now I'm looking to improve my design with some IC's and displays.
Thanks.

Hi, with "micro" you mean microprocessor? I thought of that originally, but my budget is limited with stock on hand and probably couple more inexpensive chips. I thought of using 68HC11, but those boards are expensive for my application. And I believe HC11 has intergrated 8 bit ADC. would you happen to have some kind of schematic and parts list for your approach? Thanks.
