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 1.0µVP-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.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
4. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. For θJC, the “case temp” location is taken at the package top center.
6. Post-reflow drift for the ISL21090 devices can exceed 100µV to 1.0mV based on experimental results with devices on FR4 double sided boards. The
system engineer must take this into account when considering the reference voltage after assembly.
Electrical Specifications VIN = 5V (1.25V option), IOUT = 0, CL = 0.1µF and CC = 0.01µF, unless otherwise specified. Boldface limits apply
over the operating temperature range, -40°C to +125°C.
