ЦАП , 16 бит, 2 Мвыборок/с, Последовательный, 2.7В до 5.5В, TSSOP, 16 вывод(-ов)

The DAC8812IBPW is a dual 16-bit current-output Digital-to-analog Converter (DAC) designed to operate from a single 2.7 to 5.5V 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 DAC outputs from previously loaded input registers. Additionally, an internal power-on reset forces the output voltage to zero at system turn-on.
