Features
• Reference Voltages . . .1.024V, 1.2V, 1.25V, 1.8V, 2.048V,
2.5V, 3.0V 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 350nA 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
- ISL60002-30. . . . . . . . . . . . . . . . . . . . . . . . 3.2V to 5.5V
- ISL60002-33. . . . . . . . . . . . . . . . . . . . . . . . 3.5V to 5.5V
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.

Applications Information
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.
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.

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 116.
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.

Noise Performance and Reduction
Turn-On Time
The output noise voltage in a 0.1Hz to 10Hz bandwidth is
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.

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 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

the 1kHz to 100kHz band can be further reduced using a
