ADR1399
Oven-Compensated, Buried Zener, 7.05 V Voltage Reference
FEATURES PIN CONFIGURATION
► 7.05 V ultrastable shunt reference ► Low temperature coefficient: 0.2 ppm/℃ ► Maximum dynamic impedance: 0.08 Ω ► Typical reference noise for 10 Hz < f < 1 kHz: 1.84 μV rms ► Initial accuracy range: –300 mV to +250 mV ► Available in 4-lead TO-46 metal can ► External thermal insulator provided ► Upgrade path for legacy LM399
Figure 1. APPLICATIONS
► Precision voltage reference for multimeters ► Calibration equipment voltage standards ► Laboratory measurement equipment ► Industrial monitor and control instrumentation ► Ultrastable data convertors
GENERAL 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 much 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. Ideal applications for the ADR1399 include ultrastable digital voltmeters, precision calibration equipment, and ultrarepeatable analog-to-digital converters (ADCs). The simplicity of the basic pin configuration is shown in Figure 1.
