Texas Instruments DAC8802

14-Bit Dual Channel Serial Interface Multiplying Digital-to-Analog Converter

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 (CSLDACRS
