ISL71090SEH25

Radiation Hardened Ultra Low Noise, Precision Voltage Reference

OVERVIEW

The ISL71090SEH25 is an ultra low noise, high DC accuracy precision voltage reference with a wide input voltage range from 4V to 30V. The ISL71090SEH25 uses the Intersil Advanced Bipolar technology to achieve 2µVP-P noise at 0.1Hz with an accuracy over temperature of 0.15%.

The ISL71090SEH25 offers a 2.5V 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 ISL71090SEH25 is ideal for high-end instrumentation, data acquisition and applications requiring high DC precision where low noise performance is critical.
