TYPICAL APPLICATION
DESCRIPTION
The X60008-25 FGA™ voltage references are very
high precision analog voltage references fabricated in
Intersil’s proprietary Floating Gate Analog technology,
which achieves superior levels of performance when
compared to conventional band gap, buried zener, or
X
FET
™ technologies.
FGA™ voltage references feature very high initial
accuracy, very low temperature coefficient, excellent
long term stability, low noise and excellent line and
load regulation, at the lowest power consumption
currently available. These voltage references enable
advanced applications for precision industrial &
portable systems operating at significantly higher
accuracy and lower power levels than can be achieved
with conventional technologies.

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.

COMMENT
Absolute Maximum Ratings are limits which may result
in impaired reliability and/or permanent damage to the
device. These are stress ratings provided for informa-
tion only and functional operation of the device at
these or any other conditions beyond those indicated
in the operational sections of this specification are not
implied.
For guaranteed specifications and test conditions, see
Electrical Characteristics.
The guaranteed specifications apply only for the test
conditions listed. Some performance characteristics
may degrade when the device is not operated under
the listed test conditions.

1. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in V
OUT
is divided
by the temperature range; in this case, -40°C to +85°C = 125°C.
2. Thermal Hysteresis is the change in V
OUT
created by package stress @ T
A
= 25°C after temperature cycling. V
OUT
is read initially at
T
A
= 25°C; the X60008 is then cycled between Hot (85°C) and Cold (-40°C) before a second V
OUT
measurement is taken at 25°C. The
deviation between the initial V
OUT
reading and the second V
OUT
reading is then expressed in ppm.
3. Guaranteed by device characterization and/or correlation to other device tests.
