ISL71090SEH12EV1Z, ISL71090SEH25EV1Z

Radiation Hardened Ultra Low Noise, Precision Voltage Reference Evaluation Board


The ISL71090SEH12EV1Z and ISL71090SEH25EV1Z evaluation boards are designed to measure the performance of the radiation hardened ultra low noise, high precision ISL71090SEH voltage reference family. The reference has a wide input voltage range from 4V to 30V and an initial accuracy of 0.05%. Its ul tra low voltage noise (1μV P-P in the 0.1Hz to 10Hz range - ISL71090SEH12); a maximum output voltage temperature coefficient of 10ppm/°C and excellent radiation performance make the ISL71090SEH ideal for space applications.
