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 1.1µVP-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.
