Ultra Low Noise, Precision Voltage Reference

ISL21090

The ISL21090 is a ultra low noise, high DC accuracy precision

voltage reference with wide input voltage range from 4.7V to

36V. The ISL21090 uses the new Intersil Advanced Bipolar

technology to achieve sub 2µV

voltage accuracy of 0.02%.

The ISL21090 offers a 2.5V output voltage option with

7ppm/°C temperature coefficient and also provides excellent

line and load regulation. The device is 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.
