DAC for 1 - 5V Signal
Hey there CE members!
I'm currently building and coding up my final project for my Electrical Technology class and I'm making a PID controller using a PIC18F452. I want to use a DAC to convert the final 8 bit value to a 1 to 5 volt signal which I will then convert to a 4 - 20mA signal.
At the moment I have a #-Link-Snipped-# chip which I'm having a little trouble with wiring. I also have access to a #-Link-Snipped-# which I can use on SPI.
The trouble I'm having with the DAC0808 is the Io, Vee, and Vref- pins. I think that the Io pin is where my output voltage will be taken from, but as to the Vee and Vref- pins I'm totally lost.
Another question I have is will I be able to get a 1 to 5 volt signal out of either of these, or will I have to use a 0 to 5 volt signal. I'd prefer to use the DAC0808 to the the SPI chip for now, but any other suggestions on other chips that are available would be a big help!
