DATASHEET
ISL21007
Precision, Low Noise FGA Voltage References
The
ISL21007
FGA™ voltage references are extremely low
power, high precision, and low noise voltage references
fabricated on Intersil’s proprietary Floating Gate Analog (FGA)
technology. The ISL21007 features very low noise (4.5µV
P-P
for
0.1Hz to 10Hz) and very low operating current (150µA, Max). In
addition, the ISL21007 family features guaranteed initial
accuracy as low as ±0.5mV.
This combination of high initial accuracy, low drift, and low
output noise performance of the ISL21007 enables versatile
high performance control and data acquisition applications
with low power consumption.

NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
2. Add “-TK” suffix for 1k unit tape and reel option. Refer to
TB347
for details on reel specifications.
3. For Moisture Sensitivity Level (MSL), see device information pages for
ISL21007CFB812, ISL21007CFB820, ISL21007CFB825, ISL21007CFB830,
ISL21007DFB812, ISL21007DFB820, ISL21007DFB825, ISL21007DFB830.

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.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted,
all tests are at the specified temperature and are pulsed tests, therefore: T

NOTES:
4. Measured with no filtering, distance of 10” from source, intensity set to 55kV and 70mA current, 30s duration. Other exposure levels should be
analyzed for Output Voltage drift effects. See
“Applications Information” on page 16.
5.
JA
is measured with the component mounted on a high-effective thermal conductivity test board in free air. See tech brief
TB379
for details.
6. Post-reflow drift for the ISL21007 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.
