ISL71091SEH20 FN8632
Rev 2.00
March 17, 2016 2.048V Radiation Hardened Ultra Low Noise, Precision Voltage Reference
The ISL71091SEH20 is an ultra low noise, high DC accuracy
precision voltage reference with a wide input voltage range
from 4.2V to 30V. It uses Intersil’s advanced bipolar technology
to achieve 3.8ВµVP-P 0.1Hz to 10Hz noise with an initial voltage
accuracy of 0.05%. Features The ISL71091SEH20 offers a 2.048V output voltage option
with 6ppm/В°C temperature coefficient and also provides
excellent line and load regulation. The device is offered in an
8 Ld flatpack package. Output voltage noise 3.8ВµVP-P typical (0.1Hz to 10Hz) The ISL71091SEH20 is ideal for high-end instrumentation,
data acquisition and processing applications requiring high DC
precision where low noise performance is critical. Output current capability . 10mA/-5mA Applications Reference output voltage . .2.048V В±0.05% Accuracy over temperature .
