DESCRIPTION
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
amplifier.
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.
For a 16-bit, pin-compatible version, see the
DAC8822.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.
