General description :
Intersil's revolutionary FGA™ (Floating Gate Array) voltage reference technology eclipses the performance of conventional band-gap and buried Zener references. Unlike familiar band-gap and buried Zener technologies, FGA voltage references are not dependent on the voltage produced by a silicon junction. FGA technology produces extraordinary accurate and stable reference voltages by storing a precise charge on a floating gate cell that is essentially unaffected by external influences such as variation in temperature, input voltage, and time. Standard voltage reference performance is pushed to unprecedented highs with a portfolio of products that feature the highest accuracy and stability in the industry - and at power consumption that is undeniably the lowest in the industry - bar none!
