TI’s 12-bit, 8-channel, I2C-interface DAC targets multi-channel, high-density applications

The DAC7678 is the first 8-channel DAC from TI with a 2-wire I2C interface, which simplifies layout and minimizes design time. The DAC7678 includes integrated output buffer amplifiers and 2.5-V internal reference, and it can be configured to reset to zero or mid-scale.

Key features and benefits:

• High channel count integration, I2C interface, and integrated precision reference simplify layout and minimize design time for high-density applications, while a 24-pin, 4-mm x 4-mm QFN package saves board space, making it suitable for portable applications.

• Integrated precision reference with low drift, +/- 5 mV initial accuracy and 20-mA sink/source capability eliminates the need for external reference, saving board space and cost.

• Excellent low-power performance of 0.13 mA/channel at 5 V allows designers to achieve high accuracy of +/- 1 LSB maximum INL, settling time of 7 us and ultra-low glitch of 0.15 nV-s.

• Fully characterized over a wide temperature range of -40 C to 125 C for use in industrial applications.
