DESCRIPTION
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.
The DAC8871 provides excellent linearity (1LSB INL),
low noise, and fast settling (1ms 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 or 5V SPI serial interface to communicate with the
DSP or microprocessors. For optimum performance,
a set of Kelvin connections to external reference are
provided.
The DAC8871 is available in a TSSOP-16 package.
