ADR1399: Oven-Compensated, Buried Zener, 7.05V Voltage Reference
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 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
