2. Guaranteed by device characterization and/or correlation to other device tests.
3. 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.

Noise Performance and Reduction
FGA Technology
The output noise voltage in a 0.1Hz to 10Hz bandwidth is
The ISL21032 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).
typically 30µV . The noise measurement is made with a
P-P
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. Wideband noise is reduced by adding capacitor
to the output, but the value should be limited to 1nF or less
to insure stability.
Temperature Drift
The limits stated for output accuracy over temperature are
governed by the method of measurement. For the -40°C to
130°C temperature range, measurements are made at 25°C
and the two extremes. This measurement method combined
with the fact that FGA references have a fairly linear
temperature drift characteristic insures that the limits stated
will not be exceeded over the temperature range.
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
2N2905
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.
