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. The ISL21090
uses the new Intersil Advanced Bipolar technology to achieve
sub 1.0μV P-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.
