Precision, Low Noise FGA Voltage References

The ISL21007 FGA™ voltage references are extremely low power, high precision, and low noise voltage references fabricated on Intersil’s proprietary Floating Gate Analog (FGA) technology. The ISL21007 features very low noise (4.5µVP-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.
