The ISL21090 is a ultra low noise, high DC accuracy precision voltage reference with wide input voltage range. The ISL21090 uses the new Intersil Advanced Bipolar technology to achieve sub 1. 0µVP-P (1. 25V option) 0. 1Hz to 10Hz noise with an initial voltage accuracy of 0. 02% (2. 5V option). The ISL21090 offers 1. 25V, 2. 5V, 5. 0V and 7. 5V output voltage options with 7ppm/°C temperature coefficient and also provides excellent line and load regulation. These devices are offered in an 8 Ld SOIC package. The ISL21090 is ideal for high-end instrumentation, data acquisition and processing applications requiring high DC precision where low noise performance is critical.
