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 longterm stability. The ADR293-EP 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 Rev. A 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-EP is specified over the military temperature range of –55°C to +125°C. This device is available in an 8-lead TSSOP package. Additional applications information is available in the ADR293 data sheet. Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.

This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. θJA is specified for worst-case conditions; that is, θJA is specified for the device in socket testing. In practice, θJA is specified for the device soldered in a circuit board. Table 5. Thermal Resistance Package Type 8-Lead TSSOP (RU-8) ESD CAUTION Rev.
