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

1μVP-P (0.1Hz 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.

The ISL21010 is a precision, low dropout micropower

bandgap voltage reference in a space-saving SOT-23

package. It operates from a single 2.2V to 5.5V supply

(minimum voltage is dependent on voltage option)

and provides a ±0.2% accurate reference.
