DESCRIPTION
The DAC8822 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 midscale code when RSTSEL = '1'. Additionally,
an internal power-on reset forces all registers to zero
or midscale code at power-up, depending on the
state of the RSTSEL pin.
A parallel interface offers high-speed
communications. The DAC8822 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 14-bit, pin-compatible version, see the
DAC8805.
