Rev 4.00
March 18, 2016 1.25V Radiation Hardened Ultra Low Noise, Precision Voltage Reference
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 1ВµVP-P noise at 0.1Hz
with an accuracy over temperature of 0.15% and an accuracy
over radiation of 0.15%.
The ISL71090SEH12 offers a 1.25V output voltage with
10ppm/В°C temperature coefficient and also provides
excellent line and load regulation. The device is offered in an
8 Ld flatpack package.
