DESCRIPTION
The X60003x-41 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
XFET™ 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 indicate limits beyond
which permanent damage to the device and impaired
reliability may occur. These are stress ratings provided
for information only and functional operation of the
device at these or any other conditions beyond those
indicated in the operational sections of this specifica-
tion 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.

Note:
1. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in VOUT is divided
by the temperature range; in this case, -40°C to +85°C = 125°C.
2. Thermal Hysteresis is the change in VOUT created by package stress @ TA = 25°C after temperature cycling. VOUT is read initially at
TA = 25°C; the X60003x-41 is then cycled between Hot (85°C) and Cold (-40°C) before a second VOUT measurement is taken at 25°C.
The deviation between the initial VOUT reading and the second VOUT reading is then expressed in ppm.
3. Guaranteed by Device Characterization and/or correlation to other device tests.
