The DAC8871 is a 16-bit, single-channel, serial input, voltage output digital-to-analog converter (DAC). The output range is determined by the reference voltage, VREFH and VREFL. By properly selecting the reference, the output can be unipolar or bipolar, and up to 18V. These converters provide excellent linearity (1LSB INL), low noise, and fast settling (1s to 1LSB of full scale output) over the specified temperature range of 40C to +105C. The output is unbuffered, which reduces the power consumption and the error introduced by the buffer. The device features a standard high-speed clock (up to 50MHz), and a 3V or 5V SPI serial interface to communicate with the DSP or microprocessors.
