DAC8802 说明

The DAC8802 is a dual, 14-bit, current-output digital-to-analogconverter (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 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). A common level-sensitive load DAC strobe (LDAC) input allows simultaneous update of all DAC outputs from previously loaded input registers. Additionally, an internal power-on reset forces the output voltage to zero at system turn-on.
