Sep 29, 2017 Ultra Low Noise, 5V Precision Voltage Reference The ISL71010B50 is an ultra low noise, high DC
accuracy precision voltage reference, with a wide input
voltage range from 7.0V to 30V. The ISL71010B50 uses
the dielectrically isolated PR40 process to achieve
4.2ВµVP-P noise at 0.1Hz to 10Hz with an initial voltage
accuracy of В±0.05%. Features Reference output voltage: 5.0V В±0.05% Accuracy over temperature/radiation: В±0.15% Output voltage noise: 4.2ВµVP-P typical (0.1Hz to
10Hz) The ISL71010B50 offers a 5.0V output voltage with
10ppm/В°C temperature coefficient and also provides
excellent line and load regulation. The device is offered
in an 8 Ld SOIC package. Supply current: 930ВµA (typical) The ISL71010B50 is ideal for high-end instrumentation,
data acquisition, and processing applications requiring
high DC precision where low noise performance is
critical. Line regulation: 20ppm/V (maximum) Applications Dielectrically isolated PR40 process Temperature coefficient: 10ppm/В°C (maximum) Output current capability: 20mA Load regulation: 17ppm/mA (maximum) NiPdAu-Ag lead finish (Sn Free) Low Earth Orbit (LEO) Operating temperature range: -55В°C to +125В°C High altitude avionics Characterized radiation level Precision instruments Low dose rate (10mrad(Si): 30 krad(Si) Data acquisition systems for space applications Single event burnout LET: 43MeVcm2/mg Related Literature Strain and pressure gauges for space applications For a full list of related documents, visit our website Active sources for sensors ISL71010B50 product page. 2
