OVERVIEW
The ISL71091SEH40 is an ultra low noise, high DC accuracy precision voltage reference with a wide input voltage range from 6.0V to 30V. It uses Intersil’s advanced bipolar technology to achieve 6.2μVP-P
0.1Hz to 10Hz noise with an initial voltage accuracy of 0.05%.
The ISL71091SEH40 offers a 4.096V 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 ISL71091SEH40 is ideal for high-end instrumentation, data acquisition and processing applications requiring high DC precision where low noise performance is critical.
