1 / 13 page 1 DATASHEET Radiation Hardened Ultra Low Noise, Precision Voltage Reference ISL71090SEH50 The ISL71090SEH50 is an ultra low noise, high DC accuracy precision voltage reference with a wide input voltage range from 7V to 30V. The ISL71090SEH50 uses the Intersil 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. The ISL71090SEH50 is ideal for high-end instrumentation, data acquisition and applications requiring high DC precision where low noise performance is critical. Applications • RH voltage regulators precision outputs • Precision voltage sources for data acquisition system for space applications • Strain and pressure gauge for space applications Related Literature • AN1847, “ISL71090SEH12EV1Z, ISL71090SEH25EV1Z, ISL71090SEH50EV1Z, ISL71090SEH75EV1Z User Guide” • AN1848, “Single Event Effects (SEE) Testing of the ISL71090SEH Precision Voltage Reference” • AN1849, “Total Dose Testing of the ISL71090SEH Precision Voltage Reference” Features • Reference output voltage . . . . . . . . . . . . . . . . . . 5.0V ±0.05% • Accuracy over temperature . . . . . . . . . . . . . . . . . . . . .±0.15% • Output voltage noise . . . . . .1.1µVP-P typical (0.1Hz to 10Hz) • Supply current . . . . . . . . . . . . . . . . . . . . . . . . . . 930µA (typical) • Tempco (box method) . . . . . . . . . . . . . .10ppm/°C maximum • Output current capability . . . . . . . . . . . . . . . . . . . . . . . . 20mA • Line regulation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .8ppm/V • Load regulation . . . . . . . . . . . . . . . . . . . . . . . . . . . .10ppm/mA • Operating temperature range. . . . . . . . . . . .-55°C to +125°C • Radiation environment - High dose rate (50-300rad(Si)/s) . . . . . . . . . . . 100krad(Si) - Low dose rate (0.01rad(Si)/s) . . . . . . . . . . . . . 100krad(Si)* - SET/SEL/SEB . . . . . . . . . . . . . . . . . . . . . . .86MeV•cm2/mg *Product capability established by initial characterization.
