Product Summary
The ADR293 is a low noise, micropower precision voltage reference that utilizes an XFET. (eXtra implanted junction FET) reference circuit. The new XFET architecture offers significant performance improvements over traditional bandgap and Zener-based references. Improvements include: one quarter the voltage noise output of bandgap references operating at the same current, very low and ultralinear temperature drift, low thermal hysteresis and excellent long-term stability. The ADR293 is a series voltage reference providing stable and accurate output voltage from a 6.0 V supply. Quiescent current is only 15 mA max, making this device ideal for battery powered instrumentation. Three electrical grades are available offering initial output accuracy of ±3 mV, ±6 mV, and ±10 mV. Temperature coefficients for the three grades are 8 ppm/℃, 15 ppm/℃ and 25 ppm/℃ max. Line regulation and load regulation are typically 30 ppm/V and 30 ppm/mA, maintaining the reference’s overall high performance. The ADR293 is specified over the extended industrial temperature range of -40℃ to +125℃. This device is available in the 8-lead SOIC, 8-lead TSSOP and the TO-92 package.
