Texas Instruments has introduced a 12-bit, 8-channel digital-to-analog converter (DAC) with I²C interface for multichannel, high-density applications such as power amplifier control in wireless base stations, portable instrumentation, data acquisition systems and laser bias control. The DAC7678 is the first 8-channel DAC from TI with a 2-wire I²C interface, which simplifies layout and minimises design time. The device includes integrated output buffer amplifiers and 2,5 V internal reference, and it can be configured to reset to zero or midscale.
The DAC’s 24-pin, 4 x 4 mm QFN package saves board space, making it suitable for portable applications. An integrated precision reference with low drift, ±5 mV initial accuracy and 20 mA sink/source capability eliminates the need for an external reference. 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 μs and ultra-low glitch of 0,15 nV-s. The DAC7678 is fully characterised over a wide temperature range of -40°C to 125°C for use in industrial applications.
