ISL71091SEH10

10V Radiation Hardened Ultra Low Noise, Precision Voltage Reference

OVERVIEW

The ISL71091SEH10 is an ultra low noise, high DC accuracy precision voltage reference with a wide input voltage range from 12V to 30V. It uses Intersil’s advanced bipolar technology to achieve 14.8μVP-P 0.1Hz to 10Hz noise with an initial voltage accuracy of 0.05%.

The ISL71091SEH10 offers a 10.0V 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 ISL71091SEH10 is ideal for high-end instrumentation, data acquisition and processing applications requiring high DC precision where low noise performance is critical.
