2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThe DAC7612 is a dual, 12-bit digital-to-analog converter (DAC) with guaranteed
4*4882a593Smuzhiyun12-bit monotonicity performance over the industrial temperature range.
5*4882a593SmuzhiyunIs is programmable through an SPI interface.
6*4882a593Smuzhiyun
7*4882a593SmuzhiyunThe internal DACs are loaded when the LOADDACS pin is pulled down.
