  • The RHF1009A is a low-power adjustable 2.5 V voltage reference, specifically designed to sustain radiations in space applications.

    Mounted in a Flat-10 ceramic package, the RHF1009A uses a dedicated architecture and design rules to provide the best immunity against heavy-ions.
    A very low operating current and very good stability over a wide temperature range of -55°C to +125°C make the RHF1009A particularly suitable for precision and power saving.

    Key Features

    • Adjustable shunt, 2.5 V to 5.5 V
    • High precision ±0.2% at 2.5 V at 25 °C
    • Wide operating current: 60 μA to 12 mA
    • 30 ppm/°C maximum temperature range at 2.5 V
    • Stable on capacitive load
    • ELDRS-free up to 300 krad
    • 300 krad high/low dose rate
    • SEL-free up to 120 MeV.cm²/mg
    • SET characterized
