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 400nA operating
current.
Additional features include guaranteed initial accuracy as
low as ±1.0mV, @ 20ppm/°C temperature coefficient and
long-term stability of <<10ppm/√1kHrs. The initial accuracy
and thermal stability performance of the ISL60002 family
plus the low supply voltage and 400nA 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.
