Precision 5.0V FGA™ Voltage Reference
X60008E-50
FEATURES
DESCRIPTION
• Output Voltage: 5.000V
The X60008-50 FGA™ voltage references are very
• Absolute Initial Accuracy = ±5mV
high precision analog voltage references fabricated in
• Ultra Low Power Supply Current: 500nA
Xicor’s proprietary Floating Gate Analog technology,
which achieves superior levels of performance when
• Low Temperature Coefficient = 20ppm/°C max
compared to conventional band gap, buried zener, or
• 10 mA Source & Sink Current Capability
• 10 ppm/1000hrs Long Term Stability
m• Very Low Dropout Voltage: 100 mV @ no load
o• Supply Voltage Range: 5.1V to 9.0V
• 5kV ESD (Human Body Model)
.c• Standard Package: SOIC-8
U• Temp Range: -40°C to +85°C
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.

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 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.
3. Dropout voltage (VDO) is the minimum voltage (VIN) into the X60008 which will produce the output voltage (VOUT) drop specified in
the Electrical Characteristics table.
