3 Description
The DAC8812 is a dual, 16-bit, current-output digitalto-analog converter (DAC) designed to operate from a single 2.7-V to 5.5-V supply.
The applied external reference input voltage VREF determines the full-scale output current. An internal feedback resistor (RFB) provides temperature tracking for the full-scale output when bined with an external I-to-V precision amplifier.
A double-buffered, serial data interface offers...
