Hi,
I am working on a project in which I have to invert the voltage from a DAC that I have chosen. This DAC works from an I2C bus; however it can only produce voltages from 0-5V, I would like to be able to invert this output and make it from -5V to 0V. I know I can build an inverter buffer using Op-Amps however my end goal is to be able to produce outputs from -5V to 5V. I believe there is an IC capable of turning my positive voltage and convert it into negative voltage if I choose so. I haven't been able to find this IC unfortunately, nor I2C DAC that produce negative and positive voltages with 14 bit or higher resolution.
Thanks in Advance.
