Texas Instruments Launches Accuracy DAC in QFN-24 Package

Texas Instruments Incorporated (TI) has introduced its digital-to-analog converter (DAC), which features 18-bit monotonic performance, ±2 LSB integral nonlinearity (INL), ±1 LSB differential nonlinearity (DNL). Delivered in a small QFN-24 package, the DAC9881 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 DAC9881 is a single-channel, voltage-output DAC with an on-chip, low-noise output buffer, which reduces the number of external components required. The device supports a SPI serial interface capable of operating with input data clock frequencies up to 50 MHz for a fast and flexible interface to the most popular DSPs, MCUs and FPGAs. The DAC combines low power consumption (4 mW at 5 V) and small packaging (QFN-24) to allow higher density board layouts. Other key features include 24 nV/rtHz noise, 5-µs settling time, rail-to-rail output swing over the full supply range of 2.7 V to 5.5 V and selectable power-on reset to zero-scale or midscale. The DAC9881 is available now from TI and its authorized distributors in a QFN-24 package (4mm x 4mm). Suggested resale pricing starts at $16.90 each in 1,000-piece quantities.
