High Voltage Input Precision, Low Noise
FGA™ Voltage References
The ISL21009 FGA™ voltage references are extremely low
power, high precision, and low noise voltage references
fabricated on Intersil’s proprietary Floating Gate Analog
technology. The ISL21009 features very low noise (4.5µV
for 0.1Hz to 10Hz), low operating current (180µA, Max), and
3ppm/°C of temperature drift. In addition, the ISL21009
family features guaranteed initial accuracy as low as
±0.5mV.
This combination of high initial accuracy, low power and low
output noise performance of the ISL21009 enables versatile
high performance control and data acquisition applications
with low power consumption.
