The DAC8820, a multiplying digital-to-analog
1.66 mA Full-Scale Current,
converter (DAC), is designed to operate from a single
with V

= 10 V
2.7 V to 5.5 V supply.
Settling Time: 0.5 µ s
The applied external reference input voltage V
REF
4-Quadrant Multiplying Reference
determines the full-scale output current. An internal
feedback resistor (R
FB
) provides temperature tracking
Reference Bandwidth: 8 MHz
for the full-scale output when combined with an
Reference Input: ± 15 V
external, current-to-voltage (I/V) precision amplifier.
Reference Dynamics: 105 dB THD
A parallel interface offers high-speed
SSOP-28 Package
communications. The DAC8820 is packaged in a
Industry-Standard Pin Configuration
space-saving SSOP-28 package and has an
industry-standard pinout.
