Hot-selling and scarce ADR291ERZ Series Voltage Reference IC Fixed 2.5V V ±0.08% 5 mA 8-SOIC spot stock
ADR291ERZ Series Voltage Reference IC Fixed 2.5V V ±0.08% 5 mA 8-SOIC spot stock
Product Descriptions
The ADR291 and ADR292 are low noise,micropower precision voltage references that use an XFET® reference circuit. The new XFET architecture offers significant performance improvements over traditional band gap and buried Zener-based references. Improvements include one quarter the voltage noise output of band gap references operating at the same current,very low and ultralinear temperature drift, low thermal hysteresis, and excellent long-term stability.
The ADR291/ADR292 family is a series of voltage references providing stable and accurate output voltages from supplies as low as 2.8 V for the ADR291 . Output voltage options are 2.5 Vand 4.096 V for the ADR291 and ADR292, respectively.
