Features
• Reference Voltages . . .1.024V, 1.2V, 1.25V, 1.8V, 2.048V,
2.5V and 3.3V
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 400nA operating
current.
• Absolute Initial Accuracy Options. . . . . . ±1.0mV,±2.5mV,
and ±5.0mV
• Supply Voltage Range
- ISL60002-10, -11, -12, -18, -20, -25 . . . . . . 2.7V to 5.5V
- ISL60002-33. . . . . . . . . . . . . . . . . . . . . . . . 3.5V to 5.5V
Additional features include guaranteed initial accuracy as
low as ±1.0mV, @ 20ppm/°C temperature coefficient and
long-term stability of <<10ppm/√1kHrs. The initial accuracy
and thermal stability performance of the ISL60002 family
plus the low supply voltage and 400nA 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.

at T = +25°C for the device under test. The device is temperature cycled and a second V
measurement is taken at +25°C. The difference

A
3. Guaranteed by device characterization and/or correlation to other device tests.
4. FGA™ voltage reference long term drift is a logarithmic characteristic. Changes that occur after the first few hundred hours of operation are
significantly smaller with time, asymptotically approaching zero beyond 2000 hours. Because of this decreasing characteristic, long-term drift is
specified in ppm/√1kHr.
5. Pb-free manufacturing can result in solder reflow temperatures exceeding the +225°C absolute maximum. Exposing the device to this reflow
temperature will not damage it or cause any functional issues and the device will operate normally. The high reflow temperature may result in
a permanent shift in output voltage of 500µV to 1.0mV depending on the temperature and exposure time. If possible, using a reduced reflow
temperature in production will result in the best possible output voltage accuracy.

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).

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.
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.
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.
Noise Performance and Reduction
The output noise voltage in a 0.1Hz to 10Hz bandwidth is
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.
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,
P-P
as shown in Figure 100. 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 100 also shows the
noise in the 10kHz to 1MHz band can be reduced to about
In particular, battery powered data converter circuits that
would normally require the entire circuit to be disabled when
not in use can remain powered up between conversions as
shown in Figure 99. 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.

using a 0.001µF capacitor on the output. Noise in
P-P
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
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.
capacitances above 0.001µF the noise reduction network
shown in Figure 101 is recommended. This network reduces
noise significantly over the full bandwidth. As shown in
Figure 100, noise is reduced to less than 40µV
from 1Hz
P-P
to 1MHz using this network with a 0.01µF capacitor and a
2kΩ resistor in series with a 10µF capacitor.

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 102. 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.

Temperature Coefficient
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 total variation, (V
– V ), and
LOW

divide by the temperature extremes of measurement
(T

). The result is divided by the nominal

reference voltage (at T = 25°C) and multiplied by 10 to yield

coefficient.
