ISL21009
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
P-P
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.
