DESCRIPTION
This monolithic digital-to-analog converter is pin-for-
pin equivalent to the industry standard DAC80 first
introduced by Burr-Brown. Its single-chip design in-
cludes the output amplifier and provides a highly
stable reference capable of supplying up to 2.5mA to
an external load without degradation of D/A perfor-
mance.
This converter uses proven circuit techniques to pro-
vide accurate and reliable performance over tempera-
ture and power supply variations. The use of a buried
zener diode as the basis for the internal reference
contributes to the high stability and low noise of the
device. Advanced methods of laser trimming result in
precision output current and output amplifier feedback
resistors, as well as low integral and differential lin-
earity errors. Innovative circuit design enables the
DAC80 to operate at supply voltages as low as
±
11.4V
with no loss in performance or accuracy over any
range of output voltage. The lower power dissipation
of this 118-mil by 121-mil chip results in higher
reliability and greater long term stability.
Burr-Brown has further enhanced the reliability of the
monolithic DAC80 by offering a hermetic, side-brazed,
ceramic package. In addition, ease of use has been
enhanced by eliminating the need for a +5V logic
power supply.
For applications requiring both reliability and low
cost, the DAC80P in a molded plastic package offers
the same electrical performance over temperature as
the ceramic model. The DAC80P is available with
voltage output only.
For designs that require a wider temperature range, see
Burr-Brown models DAC85H and DAC87H.
