DAC8811中文资料趋稳时间为 0.5us 的 16 位单通道串行输入乘法 DAC数据手册TI规格书

描述 Description

The DAC8811 multiplying digital-to-analog converter (DAC) is 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 serial data interface offers high-speed, three-wire microcontroller-compatible inputs using data-in (SDI), clock (CLK), and chip-select (CS). On power-up, the DAC register is filled with zeroes, and the DAC output is at zero scale. The DAC8811 is packaged in space-saving 8-lead VSON and VSSOP packages. For all available packages, see the orderable addendum at the end of the datasheet.
