Ultra Low Noise, High Precision Rad Hard Voltage Reference Evaluation Boards


The ISL71091SEHxxEV1Z evaluation boards are designed to measure the performance of the radiation hardened ultra low noise, high precision ISL71091SEH voltage reference family. There are four output voltage options in the reference family, and they have a wide input voltage range up to 30V and an initial accuracy of 0.05%. With ultra low voltage noise of 3.3µVP-P in the 0.1Hz to 10Hz range (2.048V option), a maximum output voltage temperature coefficient of 6ppm/°C, and excellent radiation performance, the ISL71091SEH is ideal for space applications.

Key Features
