X60008E-41
FN8144.1
Precision 4.096V FGA™ Voltage
Reference
The X60008-41 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 and portable systems operating at
significantly higher accuracy and lower power levels than
can be achieved with conventional technologies.

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 Specifications.
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 X60008 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.
