DESCRIPTION
The DAC8801 multiplying digital-to-analog converter
is designed to operate from a single 2.7-V to 5.5-V
supply.
The applied external reference input voltage V
REF
determines the full-scale output current. An internal
feedback resistor (R
FB
) provides temperature tracking
for the full-scale output when combined with an
external I-to-V precision amplifier.
A serial-data interface offers high-speed, three-wire
microcontroller compatible inputs using data-in (SDI),
clock (CLK), and chip select (CS).
The DAC8801 is packaged in space-saving 8-lead
SON and MSOP packages.
