    1 * Texas Instruments Dual, 12-Bit Serial Input Digital-to-Analog Converter
    2 
    3 The DAC7612 is a dual, 12-bit digital-to-analog converter (DAC) with guaranteed
    4 12-bit monotonicity performance over the industrial temperature range.
    5 Is is programmable through an SPI interface.
    6 
    7 The internal DACs are loaded when the LOADDACS pin is pulled down.
