DESCRIPTION
The DAC8806, a multiplying digital-to-analog
converter (DAC), 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, current-to-voltage (I/V) precision amplifier.
A parallel interface offers high-speed
communications. The DAC8806 is packaged in a
space-saving SSOP-28 package and has an
industry-standard pinout.
