DAC7678SPW TI DAC | 16-TSSOP | 8-Ch, 12-Bit, I2C, 2.7V-5.5V

Product Overview

The DAC7678SPW is a low-power, 12-bit, octal digital-to-analog converter (DAC) from Texas Instruments. It features eight output channels with rail-to-rail output swing, I2C interface, and operates from a single 2.7V to 5.5V supply. The device includes an internal reference (2.5V, 10 ppm/°C) and a power-on reset to zero-scale. Housed in a compact 16-TSSOP package, it is ideal for space-constrained applications requiring multiple DAC channels.
