ISL71091SEH33EV1Z中文资料INTERSIL数据手册PDF规格书

The ISL71091SEH33 is an ultra low noise, high DC accuracy

precision voltage reference with a wide input voltage range

from 4.6V to 30V. It uses Intersil’s advanced bipolar technology

to achieve 5.2µVP-P 0.1Hz to 10Hz noise with an initial voltage

accuracy of 0.05.

The ISL71091SEH33 offers a 3.3V 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 ISL71091SEH33 is ideal for high-end instrumentation,

data acquisition and processing applications requiring high DC

precision where low noise performance is critical.
