Maxim Integrated offers an industry-leading portfolio of shunt and series voltage reference ICs. We were the first to develop a series reference in a 3-pin SC70 and in chip-scale packaging. Our hundreds of voltage references include high-accuracy, low-power, low-noise, and automotive-grade products.
