16-Bit, Single-Channel, ±18V Output (Unbuffered), Ultra-Low Power, Serial Interface  
DIGITAL-TO-ANALOG CONVERTER  
FEATURES  
DESCRIPTION  
16-Bit Resolution  
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 (1µs to 1LSB of full scale output) over the  
specified temperature range of –40°C to +105°C.  
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.  
Output: ±18V for ±18V Reference Input  
±18V Supply Operation  
Very Low Power  
High Accuracy INL: 1LSB  
Low Noise: 10nV/Hz  
Fast Settling: 1µs to 1LSB  
Fast SPI™ Interface: Up To 50MHz  
16-Pin TSSOP Package  
Selectable Reset to Zero or Midscale
