The ISL71090SEH75 is an ultra low noise, high DC accuracy

precision voltage reference with a wide input voltage range

from 9.2V to 30V. The ISL71090SEH75 uses the Intersil

advanced bipolar technology to achieve 1.0µVP-P noise at

0.1Hz with an accuracy over temperature of 0.15.

The ISL71090SEH75 offers a 7.5V 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 ISL71090SEH75 is ideal for high-end instrumentation,

data acquisition and applications requiring high DC precision

where low noise performance is critical.
