1 / 13 page 1 DATASHEET 7.5V Radiation Hardened Ultra Low Noise, Precision Voltage Reference ISL71090SEH75 The ISL71090SEH75 is an ultra low noise, high DC accuracy precision voltage reference with a wide input voltage range from 9.2V to 30V. The ISL71090SEH75 uses the Intersil advanced bipolar technology to achieve 1.0µVP-P noise at 0.1Hz with an accuracy over temperature of 0.15%. The ISL71090SEH75 offers a 7.5V 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 ISL71090SEH75 is ideal for high-end instrumentation, data acquisition and applications requiring high DC precision where low noise performance is critical.
