Precision, Low Noise FGA™ Voltage References
ISL21007
The ISL21007 FGA™ voltage references are extremely low
power, high precision, and low noise voltage references
fabricated on Intersil’s proprietary Floating Gate Analog
technology. The ISL21007 features very low noise (4.5µV
P-P
for
0.1Hz to 10Hz) and very low operating current (150µA, Max). In
addition, the ISL21007 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 ISL21007 enables versatile
high performance control and data acquisition applications
with low power consumption.
