Overview
The DAC8811ICDGKT, produced by Texas Instruments, is a 16-bit, serial input multiplying digital-to-analog converter (DAC). This device is designed to operate from a single 2.7-V to 5.5-V supply, making it versatile for various applications. The DAC8811 features a high-speed, three-wire serial interface compatible with most digital signal processors (DSPs) and microcontrollers. It includes an internal feedback resistor (RFB) for temperature tracking and is packaged in space-saving 8-lead VSON and VSSOP packages. On power-up, the DAC register is filled with zeroes, and the DAC output is at zero scale, ensuring a controlled startup condition.
