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 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.

2. 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.
