DAC80P-CBI-V

Product Summary

This monolithic digital-to-analog converter DAC80P-CBI-V is pin-forpin equivalent to the industry standard DAC80 first introduced by Burr-Brown. Its single-chip design includes 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 performance. The DAC80P-CBI-V uses proven circuit techniques to provide accurate and reliable performance over temperature 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 DAC80P-CBI-V. Advanced methods of laser trimming result in precision output current and output amplifier feedback resistors, as well as low integral and differential linearity errors. Innovative circuit design enables the DAC80P-CBI-V 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.
