Ultra Low Noise,
Precision Voltage
Reference
The ISL21090 is an ultra low noise, high DC accuracy
precision voltage reference with wide input voltage
range from 3.7V to 36V. The ISL21090 uses the new
Intersil Advanced Bipolar technology to achieve sub
1μV
accuracy of 0.02%. The ISL21090 offers a 1.25V and
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.
