Selectable Reset to Zero or Midscale 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 В±18V.
The DAC8871 provides excellent linearity (1LSB INL),
low noise, and fast settling (1Вµs 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. This device features a
standard high-speed clock (up to 50MHz), and a 3V …
