3*c66ec88fSEmmanuel VadotThe DAC7612 is a dual, 12-bit digital-to-analog converter (DAC) with guaranteed
4*c66ec88fSEmmanuel Vadot12-bit monotonicity performance over the industrial temperature range.
5*c66ec88fSEmmanuel VadotIs is programmable through an SPI interface.
6*c66ec88fSEmmanuel Vadot
7*c66ec88fSEmmanuel VadotThe internal DACs are loaded when the LOADDACS pin is pulled down.
