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.
