The output range is determined by the • ±18V Supply Operation reference voltage, VREFH and VREFL. By properly • Very Low Power selecting the reference, the output can be unipolar or • High Accuracy INL: 1LSB bipolar, and up to ±18V. These converters provide excellent linearity (1LSB INL), low noise, and fast • Low Noise: 10nV/√Hz settling (1 µs to 1LSB of full scale output) over the • Fast Settling: 1µs to 1LSB specified temperature range of –40 °C to +105°C. • Fast SPI™ Interface: Up To 50MHz The output is unbuffered, which reduces the power consumption and the error introduced by the buffer. • 16-Pin TSSOP Package The device features a standard high-speed clock (up • Selectable Reset to Zero or Midscale to 50MHz), and a 3V or 5V SPI serial interface to communicate with the DSP or microprocessors. For optimum performance, a set of Kelvin • Portable Equipment connections to external reference are provided. The • Automatic Test Equipment DAC8871 is available in a TSSOP-16 package. • Industrial Process Control • Data Acquisition Systems • Optical Networking Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
