DESCRIPTION
The UCC5950 is a self-contained, microprocessor-compatible 10-bit D/A con-
verter. It contains all of the functions required to take data directly from a three-
wire serial data bus and convert it to a precise voltage, including: an input shift
register, data latches, a precision voltage reference, a precision 10-bit digital to
analog converter, and an output buffer amplifier.
The serial data interface is capable of clock frequencies as high as 20MHz, al-
lowing update rates as high as two words per microsecond. The UCC5950 ac-
cepts commands encoded as 2âs-complement binary.
The data converter in the UCC5950 is inherently monotonic, making this part
ideal for use in closed-loop servo control systems as well as open-loop data
conversion. The UCC5950 uses a unique segmented data converter which of-
fers differential linearity better than 1 LSB, integral linearity better than 2 LSB,
and fast conversion.
