The DAC8814 is a quad, 16-bit, current-output digital-to-analog converter (DAC) designed to operate from a single +2.7-V to 5.0-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 combined with an external I-to-V precision amplifier.
A doubled buffered serial data interface offers high-speed, 3-wire, SPI and microcontroller compaTIble inputs using serial data in (SDI), clock (CLK), and a chip-select (CS). In addiTIon, a serial data out pin (SDO) allows for daisy-chaining when mulTIple packages are used. A common level-sensiTIve load DAC strobe (LDAC) input allows simultaneous update of all DAC outputs from previously loaded input registers.
