Integrated overvoltage protection improves amplifier reliability and precision
April 16, 2012 // By Eric Modica and Michael Arkin
When an op amp's input voltage exceeds the specified input-voltage range, the amplifier’s output may not be accurate, but when the input voltage exceeds the power supplies, the part can be damaged.
These are both forms of overvoltage conditions that can affect the operation of the amplifier. In this article we will discuss external overvoltage protection schemes that can be used and compare them to integrated overvoltage protection, which provides designers with a more compact, robust, transparent, cost-effective solution.
