ADR293GRZ

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 ultra linear temperature drift, low thermal hysteresis, and excellent long-term stability. It is a series voltage reference providing stable and accurate output voltage from a 6V supply. Quiescent current is only 15μA maximum, making this device ideal for battery powered instrumentation. Three electrical grades are available offering initial output accuracy of ±3mV, ±6mV, and ±10mV. It is widely used in application such as portable instrumentation, precision reference for 5V systems, ADC and DAC reference, solar-powered applications, loop-current powered instruments etc.
