DAC7678SPWR TI DAC | 16-TSSOP | 8-Ch, 12-Bit, I2C, 2.7-5.5V

Product Overview

The DAC7678SPWR is a low-power, octal, 12-bit buffered voltage output digital-to-analog converter (DAC) from Texas Instruments. It operates from a single 2.7V to 5.5V supply and features an I2C-compatible serial interface. The device includes an internal reference (2.5V, 10 ppm/°C) and a power-on reset circuit that powers up the DAC outputs at zero-scale or mid-scale. The DAC7678SPWR is available in a compact 16-pin TSSOP package, making it ideal for space-constrained applications.
