DESCRIPTION
The X60008-50 FGATM 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
TM technologies.
FGATM 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.

RECOMMENDED OPERATING CONDITIONS
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.
ELECTRICAL CHARACTERISTICS
(Operating Conditions: V
IN
= 6.5V, I
OUT
= 0mA, C
OUT
= 0.001F, T
A
= -40 to +85C unless otherwise specified.)
Note:
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, -40C to +85C = 125C.
2. Thermal Hysteresis is the change in V
OUT
created by package stress @ T
A
= 25C after temperature cycling. V
OUT
is read initially at T
A
= 25C; the X60008 is then cycled between Hot (85C) and Cold (-40C) before a second V
OUT
measurement is taken at 25C. The
deviation between the initial V
OUT
reading and the second V
OUT
reading is then expressed in ppm.
3. Dropout voltage (V
DO
) is the minimum voltage (V
IN
) into the X60008 which will produce the output voltage (
V
OUT
) drop specified in the
Electrical Characteristics table.
