The DAC8805 dual, multiplying digital-to-analog
converter (DAC) is designed to operate from a single
2.7V to 5.5V supply.
The applied external reference input voltage VREF
determines the full-scale output current. An internal
feedback resistor (RFB) provides temperature
tracking for the full-scale output when combined with
an external, current-to-voltage (I/V) precision
A RSTSEL pin allows system reset assertion (RS) to
force all registers to zero code when RSTSEL = '0',
or to mid-scale code when RSTSEL = '1'.
Additionally, an internal power-on reset forces all
registers to zero or mid-scale code at power-up,
depending on the state of the RSTSEL pin.
A parallel interface offers high-speed
communications. The DAC8805 is packaged in a
space-saving TSSOP-38 package and has an
industry-standard pinout. The device is specified
from –40°C to +125°C.
