GENERAL 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.

FEATURES
6.0 V to 15 V supply range
Supply current: 15 μA maximum
Low noise: 15 μV p-p typical (0.1 Hz to 10 Hz)
High output current: 5 mA
Temperature range: −40°C to +125°C
Pin-compatible with the REF02/REF19x

APPLICATIONS
Portable instrumentation
Precision reference for 5 V systems
ADC and DAC reference
Solar-powered applications
Loop-current powered instruments
