Detailed Description
The ADR1399 precision shunt reference features excellent temperature stability over a wide range of voltage, temperature, 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 IREF of 3 mA and offers minimal noise (1.44 μV p-p, 0.1 Hz to 10 Hz) and excellent long-term stability (7 ppm/√kHr). The ADR1399 offers a lower output dynamic impedance (0.08 Ω) than the LM399, reducing the effects of shunt resistor (RSHUNT) and the supply voltage variation on the reference output.
