Rev 4.00
March 18, 2016 2.5V Radiation Hardened Ultra Low Noise, Precision Voltage Reference
The ISL71090SEH25 is an ultra low noise, high DC accuracy
precision voltage reference with a wide input voltage range
from 4V to 30V. The ISL71090SEH25 uses the Intersil
Advanced Bipolar technology to achieve 2ВµVP-P noise at 0.1Hz
with an accuracy over temperature of 0.15%. Features The ISL71090SEH25 offers a 2.5V 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. Voltage accuracy over radiation .В±0.175% The ISL71090SEH25 is ideal for high-end instrumentation,
data acquisition and applications requiring high DC precision
where low noise performance is critical.
