Description

The ADR293 is a low noise, micropower precision voltage reference that utilizes an XFET®(eXtra implanted junction FET) reference circuit. The 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 ADR293 is a series voltage reference providing stable and accurate output voltage from a 6.0 V supply. Quiescent current is only 15 μA maximum, making this device ideal for battery powered instrumentation. The temperature coefficient is 30 ppm/°C maximum over the military temperature range, and the initial error is only 0.2% at 25°C. Line regulation and load regulation are typically 70 ppm/V and 30 ppm/mA, respectively, maintaining the reference’s overall high performance.The ADR293 is specified over the military temperature range of –55°C to +125°C. This device is available in an 8-lead TSSOP package.The ADR293-EP support defense and aerospace applications (AQEC).APPLICATIONSPortable instrumentationPrecision reference for 5 V systemsADC and DAC referenceSolar-powered applications
