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
to 10Hz) noise with an initial voltage 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.
