INFORMATION

Precision 0.600V Low Voltage FGA™
References

The ISL21032 FGA™ voltage references are very high
precision analog voltage references specifically designed to
meet the rigorous performance requirements of high current,
low voltage VRM and POL modules.

Fabricated in Intersil's proprietary Floating Gate Analog
technology, these references and feature guaranteed
performance over the -40°C to 130°C operating temperature
range.

Additional features include guaranteed absolute accuracy as
low as ±0.5% over the operating temperature range of -40°C
to +130°C. Long-term stability is 10ppm/√1,000Hrs

.

The absolute accuracy and thermal performance of the
ISL21032 family are ideal fit for the next generation of high
current, low voltage VRM and POL modules.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

2. Guaranteed by device characterization and/or correlation to other device tests.

3. FGA™ voltage reference long term drift is a logarithmic characteristic. Changes that occur after the first few hundred hours of operation are
significantly smaller with time, asymptotically approaching zero beyond 2000 hours. Because of this decreasing characteristic, long-term drift is
specified in ppm/

√1kHr.
