The ISL71091SEH20 is an ultra low noise, high DC accuracy precision voltage reference with a wide input voltage range from 4. 2V to 30V. It uses Intersil’s advanced bipolar technology to achieve 3. 8μVP-P 0. 1Hz to 10Hz noise with an initial voltage accuracy of 0. 05%. The ISL71091SEH20 offers a 2. 048V output voltage option with 6ppm/°C temperature coefficient and also provides excellent line and load regulation. The device is offered in an 8 Ld flatpack package. The ISL71091SEH20 is ideal for high-end instrumentation, data acquisition and processing applications requiring high DC precision where low noise performance is critical.
