Precision Low Power FGA™ Voltage References
ISL60002
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.
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:
5. 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.
6. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
7. For JC, the “case temp” location is taken at the package top center.
8. 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.
9. 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.
