Applications Information
FGA Technology
The ISL21009MEP voltage reference uses 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).
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.
Micropower Operation
The ISL21009MEP consumes extremely low supply current
due to the proprietary FGA technology. Low noise
performance is achieved using optimized biasing
techniques. Supply current is typically 95µA and noise is
4.5µVP-P benefitting precision, low noise portable
applications such as handheld meters and instruments.
Data Converters in particular can utilize the ISL21009MEP
as an external voltage reference. Low power DAC and ADC
circuits will realize maximum resolution with lowest noise.
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

Board Mounting Considerations
Turn-On Time
For applications requiring the highest accuracy, board
mounting location should be reviewed. The device uses a
plastic SOIC package, which will subject the die to mild
stresses when the PC board is heated and cooled, slightly
changing the shape. Placing the device in areas subject to
slight twisting can cause degradation of the accuracy of the
reference voltage due to these 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. Mounting the device in a cutout also minimizes flex.
Obviously mounting the device on flexprint or extremely thin
PC material will likewise cause loss of reference accuracy.
The ISL21009MEP devices have 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 100µs. This is shown in Figure 11. Circuit
design must take this into account when looking at power-up
delays or sequencing.
Noise Performance and Reduction
The output noise voltage in a 0.1Hz to 10Hz bandwidth is
typically 4.5µVP-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.
Noise in the 10kHz to 1MHz bandwidth is approximately
40µVP-P with no capacitance on the output. This noise
measurement is 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 10x the center frequency. Load capacitance up
to 1000pF can be added but will result in only marginal
improvements in output noise and transient response. The
output stage of the ISL21009MEP is not designed to drive
heavily capactive loads, so for load capacitances above
0.001µF, the noise reduction network shown in Figure 44 is
recommended. This network reduces noise significantly over
the full bandwidth. Noise is reduced to less than 20µVP-P from
1Hz to 1MHz using this network with a 0.01µF capacitor and a
2kΩ resistor in series with a 10µF capacitor. Also, transient
response is improved with higher value output capacitor. The
0.01µF value can be increased for better load transient
response with little sacrifice in output stability.
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, (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.
Output Voltage Adjustment
The output voltage can be adjusted up or down by 2.5% by
placing a potentiometer from VOUT to GND and connecting the
wiper to the TRIM pin. The TRIM input is high impedance so no
series resistance is needed. The resistor in the potentiometer
should be a low tempco (<50ppm/°C) and the resulting voltage
divider should have very low tempco <5ppm/°C. A digital
potentiometer such as the ISL95810 provides a low tempco
resistance and excellent resistor and tempco matching for trim
applications.
