The ISL71091SEHxxEV1Z evaluation boards are designed to measure the performance of the radiation hardened ultra-low noise, high precisionISL71091SEH 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.

The boards are designed to operate at the following conditions:

  • Input voltage range:
    • 2.048V option = 4.2V to 30V
    • 3.3V option = 4.6V to 30V
    • 4.096V option = 6V to 30V
    • 10V option = 12V to 30V
  • Output current capability: Source 10mA, Sink 5mA
  • Operating temperature range: -55 °C to +125 °C


  • Small, compact design
  • Multiple connectors to easily monitor VIN and VOUT
  • Four output voltage options


  • Precision voltage sources for data acquisition systems used in space
  • Strain and pressure gauge for space applications
  • Radiation hardened PWM requiring precision outputs
