Overview
The DAC8811ICDGKRG4 is a 16-bit, serial input multiplying digital-to-analog converter (DAC) produced by Texas Instruments. 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 DSPs and microcontrollers, allowing for efficient data transfer at frequencies up to 50 MHz. On power-up, the DAC register is initialized with zeroes, setting the DAC output to zero scale. The device is packaged in compact 8-lead VSON and VSSOP packages, enhancing its suitability for space-constrained designs.
