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 32 and AN1533, “X-Ray
Effects on Intersil FGA References”.
