Overview

The ISL71090SEH50 is an ultra low noise, high DC accuracy precision voltage reference with a wide input voltage range from 7V to 30V. The ISL71090SEH50 uses the Intersil Advanced Bipolar technology to achieve 1. 1µVP-P noise at 0. 1Hz with an accuracy over-temperature of 0. 15%. The ISL71090SEH50 offers a 5. 0V 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 ISL71090SEH50 is ideal for high-end instrumentation, data acquisition and applications requiring high DC precision where low noise performance is critical.
