Industry’s highest accuracy DAC improves system performance

Tiny part delivers ±2-LSB INL and ±1 LSB DNL

Offered as the industry's highest accuracy DAC, the DAC9881 features 18-bit monotonic performance, ±2-LSB INL and ±1 LSB DNL — all in a tiny QFN-24 package. The chip reduces external components by 75% by integrating a low-noise buffer and enables customers to increase system performance and simplify designs in precision industrial applications such as automatic test equipment, instrumentation, process control, data acquisition and communications systems.

The device supports a SPI serial interface capable of operating with input data clock frequencies up to 50 MHz. Other key features include a 4-mW power consumption at 5 V, 24 nV/√Hz noise, a 5-μs settling time, rail-to-rail output swing over the full supply range of 2.7 to 5.5 V, and selectable power-on reset to zero-scale or midscale. (From $16.90 ea/1,000 — available now.)
