Precision Low Power FGA™ Voltage References
ISL60002
The ISL60002 FGA™ voltage references are very high precision
analog voltage references fabricated in Intersil's proprietary
Floating Gate Analog technology and feature low supply
voltage operation at ultra-low 350nA operating current.
Features
• Reference voltages . . . . . 1.024V, 1.2V, 1.25V, 1.8V, 2.048V,
2.5V, 2.6V, 3.0V and 3.3V
• Absolute initial accuracy options . . . . . . . . . ±1.0mV,±2.5mV
and ±5.0mV
Additionally, the ISL60002 family features guaranteed initial
accuracy as low as ±1.0mV and 20ppm/°C temperature
coefficient. The initial accuracy and temperature stability
performance of the ISL60002 family, plus the low supply
voltage and 350nA power consumption, eliminates the need
to compromise thermal stability for reduced power
consumption making it an ideal companion to high resolution,
low power data conversion systems.

NOTES:
5. 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 34.
6. θ is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
JA
7. For θ , the “case temp” location is taken at the package top center.
JC
8. Post-reflow drift for the ISL60002 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.
9. Post-assembly x-ray inspection may also lead to permanent changes in device output voltage and should be minimized or avoided. Initial accuracy
can change 10mV or more under extreme radiation. Most inspection equipment will not affect the FGA reference voltage, but if x-ray inspection is
required, it is advisable to monitor the reference output voltage to verify excessive shift has not occurred.

NOTES:
10. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
11. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in V
temperature range: (-40°C to +85°C = +125°C, or -40°C to +105°C = +145°C for the ISL60002-33).

reading is then expressed in ppm. For ΔT = +125°C, the device under is cycled from +25°C to +85°C

13. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm.
14. Short Circuit Current (to V ) for ISL60002-25 at V = 5.0V and +25°C is typically around 30mA. Shorting V

can remain powered up between conversions as shown in
Figure 117. Data acquisition circuits providing 12 to 24 bits of
accuracy can operate with the reference device continuously
biased with no power penalty, providing the highest accuracy and
lowest possible long term drift.
Applications Information
FGA Technology
The ISL60002 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).
Other reference devices consuming higher supply currents will
need to be disabled in between conversions to conserve battery
capacity. Absolute accuracy will suffer as the device is biased and
requires time to settle to its final value, or, may not actually settle
to a final value as power on time may be short.

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.

Nanopower Operation
Reference devices achieve their highest accuracy when powered
up continuously, and after initial stabilization has taken place.
This drift can be eliminated by leaving the power on continuously.
FIGURE 117.
The ISL60002 is the first high precision voltage reference with
ultra low power consumption that makes it possible to leave
power on continuously in battery operated circuits. The ISL60002
consumes extremely low supply current due to the proprietary
FGA technology. Supply current at room temperature is typically
350nA, which is 1 to 2 orders of magnitude lower than
competitive devices. Application circuits using battery power will
benefit greatly from having an accurate, stable reference, which
essentially presents no load to the battery.
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.
In particular, battery powered data converter circuits that would
normally require the entire circuit to be disabled when not in use

significantly over the full bandwidth. As shown in Figure 118,
noise is reduced to less than 40µV from 1Hz to 1MHz using
this network with a 0.01µF capacitor and a 2kΩ resistor in series
Board Assembly Considerations
P-P
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. Precautions should be taken to avoid
excessive heat or extended exposure to high reflow
with a 10µF capacitor.

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 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.
FIGURE 119. NOISE REDUCTION NETWORK
Turn-On Time
The ISL60002 devices have ultra-low supply current and thus the
time to bias up internal circuitry to final values will be longer than
with higher power references. Normal turn-on time is typically
7ms. This is shown in Figure 120. Since devices can vary in
supply current down to >300nA, turn-on time can last up to about
12ms. Care should be taken in system design to include this
delay before measurements or conversions are started.
Noise Performance and Reduction
The output noise voltage in a 0.1Hz to 10Hz bandwidth is
typically 30µV . This is shown in the plot in the Typical
P-P
Performance Curves. 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.
Noise in the 10kHz to 1MHz bandwidth is approximately
400µV
with no capacitance on the output, as shown in
P-P
Figure 118. These noise measurements are made with a 2
decade bandpass filter made of a 1 pole high-pass filter with a
corner frequency at 1/10 of the center frequency and 1-pole
low-pass filter with a corner frequency at 10 times the center
frequency. Figure 118 also shows the noise in the 10kHz to 1MHz
band can be reduced to about 50µV
using a 0.001µF
P-P
capacitor on the output. Noise in the 1kHz to 100kHz band can
be further reduced using a 0.1µF capacitor on the output, but
noise in the 1Hz to 100Hz band increases due to instability of the
very low power amplifier with a 0.1µF capacitance load. For load
capacitances above 0.001µF the noise reduction network shown
in Figure 119 is recommended. This network reduces noise

The limits stated for temperature coefficient (tempco) are
governed by the method of measurement. The overwhelming
standard for specifying the temperature drift of a reference is to
measure the reference voltage at two temperatures, take the
