ADR1399 Precision Shunt Reference | Datasheet Preview

ADI’s ADR1399 is an oven-compensated, buried Zener with a 7.05 V voltage reference. It features excellent temperature stability over a wide range of voltages, temperatures, and quiescent current conditions. A temperature stabilizing loop is incorporated with the active Zener on a monolithic substrate, which nearly eliminates changes in voltage with temperature. The subsurface Zener circuit is fully specified at a quiescent current of 3 mA and offers minimal noise and excellent long-term stability. The ADR1399 offers much lower output dynamic impedance, reducing the effects of the shunt resistor and the supply voltage variation on the reference output. Ideal applications for the ADR1399 include ultrastable digital voltmeters, precision calibration equipment, and ultra-repeatable ADCs.
