DAC8812ICPWR

双通道，串行输入16位乘法数位类比转换器 Dual, Serial Input 16-Bit Multiplying Digital-to-Analog Converter

The DAC8812 is a dual, 16-bit, current-output digital-to-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 combined with an external I-to-V precision amplifier.

A double-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 turnon. An MSB pin allows system reset assertion RS to force all registers to zero code when MSB = 0, or to midscale code when MSB = 1.
