Radiation Hardened Ultra Low Noise, Precision Voltage
Reference
ISL71090SEH12
The ISL71090SEH12 is an ultra low noise, high DC accuracy
precision voltage reference with a wide input voltage range
from 4V to 30V. The ISL71090SEH12 uses the Intersil
Advanced Bipolar technology to achieve sub 2µVP-P noise at
0.1Hz with an accuracy over temperature and radiation of
0.15%.
The ISL71090SEH12 offers a 1.25V output voltage with
10ppm/°C temperature coefficient and also provides
excellent line and load regulation. The device is offered in an
8 Ld Flatpack package.
The ISL71090SEH12 is ideal for high-end instrumentation,
data acquisition and applications requiring high DC precision
where low noise performance is critical.
Applications
• RH voltage regulators precision outputs
• Precision voltage sources for data acquisition system for
space applications
