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.
