Overview
The DAC8043UC/2K5, produced by Texas Instruments, is a 12-bit current output multiplying digital-to-analog converter (DAC). It is packaged in space-saving 8-pin SOIC and 8-pin Mini-DIP configurations. This DAC features a fast 3-wire serial interface, which minimizes digital noise feedthrough and reduces circuit board space, resulting in low power dissipation. The device operates from a single +5V power supply, making it an ideal solution for low power, small size, and high performance applications.
