I am trying to select an external DAC, but when searching through the parametric search on RS I get a bit lost. My requirements are below:
* Parallel because I want it to run off 8 I/O pins
* One output
* Standard Voltage output with no bells and whistles
I do not really understand the different multiplier and current outputs etc.
I have found this TI chip, TLC7524CD. Is this a bog standard chip and what I require?
Also are 2bit and 4bit DAC's easily accessible or do most people just go for 8bit version and only use half the pins?
