If you are starting out with data conversion, I would look at the DAC/ADC boards being sold on Ebay. For less than $2 delivered, the 4 channel adc with single channel DAC is a great learning tool. It uses the PCF8591 chip. There is tons of example code out there for it.
@natopal46 the i2c chip you mentioned is digital IO expander NOT a DAC. To get a analog output you will need to use a DAC not io. there aren't many DAC chips which outputs 0-10V, most of these outputs 0-5V. You will need build a amplifier with gain set to two.
If you are not sure how to build or dont have tools i will recommend getting a breakout board which already has all this on board.
something like this 0-10V i2C DAC https://store.ncd.io/product/1-channel- ... -i%C2%B2c/
