Overview

The ISL71090SEH50EV1Z evaluation board is designed to measure the performance of the radiation hardened ultra-low noise, high precision ISL71090SEH50 voltage reference.

The ISL71090SEH50 reference has a wide input voltage range from 7V to 30V and uses 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 and is ideal for high-end instrumentation, data acquisition and applications requiring high DC precision where low noise performance is critical.
