CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact
product reliability and result in failures not covered by warranty.
NOTES:
4. Measured with no filtering, distance of 10” from source, intensity set to 55kV and 70mA current, 30s duration. Other exposure
levels should be analyzed for Output Voltage drift effects. See “Applications Information” on page 8.
5. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief
TB379 for details.
6. Post-reflow drift for the ISL21070 devices will range from 100µV to 1.0mV based on experimental results with devices on FR4
double sided boards. The design engineer must take this into account when considering the reference voltage after assembly.

NOTES:
7. 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.
8. Thermal Hysteresis is the change of VOUT measured @ TA = +25°C after temperature cycling over a specified range, ΔTA. VOUT
is read initially at TA = +25°C for the device under test. The device is temperature cycled and a second VOUT measurement
is taken at +25°C. The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm.
For Δ TA = +125°C, the device under test is cycled from +25°C to +85°C to -40°C to +25°C.
9. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately
10ppm/√1khrs
10. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established
by characterization and are not production tested.

Applications Information
FGA Technology
The ISL21070 series of voltage references use the
floating gate technology to create references with very
low drift and supply current. Essentially, the charge
stored on a floating gate cell is set precisely in
manufacturing. The reference voltage output itself is a
buffered version of the floating gate voltage. The
resulting reference device has excellent characteristics
which are unique in the industry: very low temperature
drift, high initial accuracy, and almost zero supply
current. Also, the reference voltage itself is not limited by
voltage bandgaps or zener settings, so a wide range of
reference voltages can be programmed (standard
voltage settings are provided, but customer-specific
voltages are available).
The process used for these reference devices is a floating
gate CMOS process, and the amplifier circuitry uses
CMOS transistors for amplifier and output transistor
circuitry. While providing excellent accuracy, there are
limitations in output noise level and load regulation due
to the MOS device characteristics. These limitations are
addressed with circuit techniques discussed in other
sections.
Handling and Board Mounting
FGA references provide excellent initial accuracy and low
temperature drift at the expense of very little power
drain. There are some precautions to take to insure this
accuracy is not compromised. Excessive heat during
solder reflow can cause excessive initial accuracy drift, so
the recommended +260°C max temperature profile
should not be exceeded. Expect up to 1mV drift from the
solder reflow process.
FGA references are susceptible to excessive
X-radiation like that used in PC board manufacturing.
Initial accuracy can change 10mV or more under
extreme radiation. If an assembled board needs to be

X-rayed, care should be taken to shield the FGA
reference device.
Board Mounting Considerations
For applications requiring the highest accuracy, board
mounting location should be reviewed. Placing the device
in areas subject to slight twisting can cause degradation
of the accuracy of the reference voltage due to die
stresses. It is normally best to place the device near the
edge of a board, or the shortest side, as the axis of
bending is most limited at that location. Obviously,
mounting the device on flexprint or extremely thin PC
material will likewise cause loss of reference accuracy.
Board Assembly Considerations
FGA references provide high accuracy and low
temperature drift but some PC board assembly
precautions are necessary. Normal Output voltage shifts
of 100µV to 1mV can be expected with Pb-free reflow
profiles or wave solder on multi-layer FR4 PC boards.
Precautions should be taken to avoid excessive heat or
extended exposure to high reflow or wave solder
temperatures, this may reduce device initial accuracy.
Post-assembly x-ray inspection may also lead to
permanent changes in device output voltage and should
be minimized or avoided. If x-ray inspection is required,
it is advisable to monitor the reference output voltage to
verify excessive shift has not occurred. If large amounts
of shift are observed, it is best to add an X-ray shield
consisting of thin zinc (300µm) sheeting to allow clear
imaging, yet block x-ray energy that affects the FGA
reference.
Special Applications Considerations
In addition to post-assembly examination, there are also
other X-ray sources that may affect the FGA reference
long term accuracy. Airport screening machines contain
X-rays and will have a cumulative effect on the voltage
reference output accuracy. Carry-on luggage screening
uses low level X-rays and is not a major source of output
voltage shift, however, if a product is expected to pass
FN7599.0
March 19, 2010
ISL21070
through that type of screening over 100 times, it may
need to consider shielding with copper or aluminum.
Checked luggage X-rays are higher intensity and can
cause output voltage shift in much fewer passes, thus
devices expected to go through those machines should
definitely consider shielding. Note that just two layers of
1/2 ounce copper planes will reduce the received dose by
over 90%. The leadframe for the device which is on the
bottom also provides similar shielding.
If a device is expected to pass through luggage X-ray
machines numerous times, it is advised to mount a
2-layer (minimum) PC board on the top, and along with a
ground plane underneath will effectively shield it from 50
to 100 passes through the machine. Since these
machines vary in X-ray dose delivered, it is difficult to
produce an accurate maximum pass recommendation.
ISL21070 Used as a Low Cost Precision
Current Source
Using an N-JET and the ISL21070, a precision, low cost,
high impedance current source can be created. The
precision of the current source is largely dependent on
the tempco and accuracy of the reference. The current
setting resistor contributes less than 20% of the error.

Noise Performance and Reduction
VOUT = 2.5V
The output noise voltage in a 0.1Hz to 10Hz bandwidth is
typically 30µVP-P. The noise measurement is made with
a bandpass filter made of a 1 pole high-pass filter with a
corner frequency at 0.1Hz and a 2-pole low-pass filter
with a corner frequency at 12.6Hz to create a filter with a
9.9Hz bandwidth. Wideband noise is reduced by adding
capacitor to the output, but the value should be limited
to 1nF or less to insure stability.

Temperature Drift
The limits stated for output accuracy over-temperature
are governed by the method of measurement. For the
-40°C to 85°C temperature range, measurements are
made at +25°C and the two extremes. This
measurement method combined with the fact that FGA
references have a fairly linear temperature drift
characteristic insures that the limits stated will not be
exceeded over the temperature range.
