DATASHEET
ISL71090SEH50
Radiation Hardened Ultra Low Noise, Precision Voltage Reference
The
ISL71090SEH50
is an ultra low noise, high DC accuracy
precision voltage reference with a wide input voltage range
from 7V to 30V. The ISL71090SEH50 uses the Intersil
Advanced Bipolar technology to achieve 1.1µV
P-P
noise at
0.1Hz with an accuracy over-temperature of 0.15%.
The ISL71090SEH50 offers a 5.0V 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 ISL71090SEH50 is ideal for high-end instrumentation,
data acquisition and applications requiring high DC precision
where low noise performance is critical.
