Precision Low Power FGA™ Voltage

Features
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.
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.

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:
1. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
2. 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.

NOTES:
3. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in VOUT is divided by the
temperature range: (-40°C to +85°C = +125°C, or -40°C to +105°C = +145°C for the ISL60002-33).
4. Thermal Hysteresis is the change in 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 ΔTA = +125°C, the device under is cycled from
+25°C to +85°C to -40°C to +25°C, and for ΔTA = +145°C, the device under is cycled from +25°C to +105°C to -40°C to +25°C
5. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm.
6. Short Circuit Current (to VCC) for ISL60002-25 at VIN = 5.0V and +25°C is typically around 30mA. Shorting VOUT to VCC is not recommended
due to risk of resetting the part.

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).
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.
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.

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 116. 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.
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.

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
Post-assembly x-ray inspection may also lead to permanent
changes in device output voltage and should be minimized
or avoided. 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.

NOISE VOLTAGE (µVP-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 temperatures, which may reduce
device initial accuracy.

FIGURE 117. NOISE REDUCTION
Noise Performance and Reduction
The output noise voltage in a 0.1Hz to 10Hz bandwidth is
typically 30µVP-P. This is shown in the plot in the Typical
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 400µVP-P with no capacitance on the output,
as shown in Figure 117. 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 117 also shows the
noise in the 10kHz to 1MHz band can be reduced to about
50µVP-P using a 0.001µF 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 118 is recommended. This network reduces
noise significantly over the full bandwidth. As shown in
Figure 117, noise is reduced to less than 40µVP-P from 1Hz
to 1MHz using this network with a 0.01µF capacitor and a
2kΩ resistor in series with a 10µF capacitor.

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 119. 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
3.5
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, (VHIGH – VLOW), and
divide by the temperature extremes of measurement
(THIGH – TLOW). The result is divided by the nominal
reference voltage (at T = +25°C) and multiplied by 106 to
yield ppm/°C. This is the “Box” method for specifying
temperature coefficient.
