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 3mA and offers minimal noise and excellent long-term stability. The ADR1399 offers much lower output dynamic impedance than the LM399, reducing the effects of shunt resistor (RSHUNT) and the supply voltage variation on the reference output.
- Key Features and Benefits
- • Ultralow noise and temperature coefficient enables higher bit counts
- • Very low dynamic impedance supports high stability requirement
- • Excellent long-term stability reduces calibration frequency
- Applications
- • Instrumentation
- • Communications: 5G
- • Industrial Automation
- • General Purpose
- • Healthcare
- Evaluation Board
- The ADR1399 can be evaluated with the ADR1399H-EBZ.
