The ADR293-EP is a low noise, micropower precision voltage is 30 ppm/°C maximum over the military temperature range, reference that utilizes an XFET® (eXtra implanted junction FET) and the initial error is only 0.2% at 25°C. Line regulation and reference circuit. The XFET architecture offers significant load regulation are typically 70 ppm/V and 30 ppm/mA, performance improvements over traditional band gap and respectively, maintaining the reference’s overall high buried Zener-based references. Improvements include one performance. quarter the voltage noise output of band gap references The ADR293-EP is specified over the military temperature operating at the same current, very low and ultralinear range of –55°C to +125°C. This device is available in an 8-lead temperature drift, low thermal hysteresis, and excellent long- TSSOP package. term stability. Additional applications information is available in the ADR293 The ADR293-EP is a series voltage reference providing stable data sheet. 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
