ADR1399
Overview
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.
- 7.05 V ultrastable shunt reference
- Low temperature coefficient: 0.2 ppm/℃
- Available in 4-pin TO-46 and 8-terminal LCC
- Typical reference noise for 10 Hz < f < 1 kHz: 1.84 μV rms
- Initial accuracy range: -300 mV to +250 mV
- Low dynamic impedance: 0.04 Ω in TO-46, 0.011 Ω in LCC
- External thermal insulator provided for TO-46
- Upgrade path for legacy LM399, now also in surface-mount technology (SMT)
