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.

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.
