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, V
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 (1 s 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.
For
connections to external reference are provided. The
DAC8871 is available in a TSSOP-16 package.
