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.
