    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 .
