Rev 2.00
March 18, 2016 3.3V Radiation Hardened Ultra Low Noise, Precision Voltage Reference
The ISL71091SEH33 is an ultra low noise, high DC accuracy
precision voltage reference with a wide input voltage range
from 4.6V to 30V. It uses Intersil’s advanced bipolar technology
to achieve 5.2ВµVP-P 0.1Hz to 10Hz noise with an initial voltage
accuracy of 0.05%. Features The ISL71091SEH33 offers a 3.3V 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 5.2ВµVP-P typical (0.1Hz to 10Hz) The ISL71091SEH33 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 3.3V В±0.05% Accuracy over temperature .
