Renesas' wide selection of voltage reference (Vref) circuits offer accurate and stable reference voltages unaffected by external influences such as variation in temperature, input voltage and time.

Overview

Renesas offers a wide range of precision voltage references in both FGA™ and Band-gap technology.

Renesas' revolutionary Floating Gate Array™ (FGA™) voltage reference circuits 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.
