Overview
The DAC8814ICDBT from Texas Instruments is a quad, 16-bit, current-output digital-to-analog converter (DAC) designed for high-performance applications. This device operates from a single +2.7-V to +5.0-V supply and features a 3-wire SPI-compatible serial data interface, making it compatible with microcontrollers and other SPI devices. The DAC8814 includes four independent multiplying reference inputs and can be used in a variety of applications requiring precise analog output control.
