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 (4µVP-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 drift, and low
output noise performance of the ISL21009 enables versatile
high performance control and data acquisition applications
with low power consumption.
