Voltage References
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.
