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 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.
