DATASHEET
ISL60002
Precision Low Power FGA Voltage References
The
ISL60002
FGA voltage references are very high precision
analog voltage references fabricated in Intersil's proprietary
Floating Gate Analog (FGA) 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.
Special Note: Post-assembly x-ray inspection may lead to
permanent changes in device output voltage and should be
minimized or avoided. For further information, please see
“Applications Information” on page 34
and
AN1533,
“X-Ray
Effects on Intersil FGA References”.

NOTES:
2. Refer to
TB347
for details on reel specifications.
3. 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.
4. For Moisture Sensitivity Level (MSL), see device information page for
ISL60002.
For more information on MSL see techbrief
TB363.
5. The part marking is located on the bottom of the part.

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:
6. 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 34.
7.
JA
is measured with the component mounted on a high-effective thermal conductivity test board in free air. See Tech Brief
TB379
for details.
8. For
JC
, the “case temp” location is taken at the package top center.
9. 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.
10. Post-assembly X-ray inspection may also lead to permanent changes in device output voltage and should be minimized or avoided. Initial accuracy
can change 10mV or more under extreme radiation. 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.
