ISL71090SEH75 FN8591
Rev 3.00
March 18, 2016 7.5V Radiation Hardened Ultra Low Noise, Precision Voltage Reference
The ISL71090SEH75 is an ultra low noise, high DC accuracy
precision voltage reference with a wide input voltage range
from 9.2V to 30V. The ISL71090SEH75 uses the Intersil
advanced bipolar technology to achieve 1.0ВµVP-P noise at
0.1Hz with an accuracy over temperature of 0.15%. Features The ISL71090SEH75 offers a 7.5V 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. Supply current 930ВµA (typ) The ISL71090SEH75 is ideal for high-end instrumentation,
data acquisition and applications requiring high DC precision
where low noise performance is critical. Line regulation . .8ppm/V Applications RH voltage regulators precision outputs Precision voltage sources for data acquisition system for
