7.5V Radiation Hardened Ultra Low Noise, Precision
Voltage Reference
ISL71090SEH75
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 1.0µV_P-P noise at
0.1Hz with an accuracy over temperature of 0.15%.
The ISL71090SEH75 offers a 7.5V 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 ISL71090SEH75 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
