MCP4725 12 bit DAC and SZBK07 DC-DC converter
In this video I show you how I utilize the MCP4725 12 bit digital to analog converter. This is a very nice circuit which allows me to control the SZBK07 DC-DC converter on a very fine scale. In this demonstration I use the DAC to change the output voltage of the SZBK07 between ~0-20 V. The device behaves linear on the full scale. I am glad about this circuit because it allows me to replace the 8 bit MCP41100 and have a more precise temperature control in my digital thermostat for Peltier coolers.
