DATASHEET  
2.048V Radiation Hardened Ultra Low Noise, Precision  
Voltage Reference  
ISL71091SEH20  
Features  
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 3.8µVP-P 0.1Hz to 10Hz noise with an  
initial voltage accuracy of 0.05%.

• Operating temperature range. . . . . . . . . . . .-55°C to +125°C  
The ISL71091SEH20 offers a 2.048V output voltage option  
with 6ppm/°C temperature coefficient and also provides  
excellent line and load regulation. The device is offered in an  
8 Ld Flatpack package.  
The ISL71091SEH20 is ideal for high-end instrumentation,  
data acquisition and processing applications requiring high DC  
precision where low noise performance is critical.
