The AMC1266 data sheet provides comprehensive information on the AMC1266, a precision isolation amplifier with a fully-differential output separated from the input circuitry by a silicon dioxide (SiO2) barrier. The input voltage range is ±250mV and is optimized for shunt resistors, making it suitable for a range of applications. The amplifier boasts very low nonlinearity, with a maximum of 0.075% at 5V, ensuring accurate and reliable performance. The data sheet includes detailed specifications, features, and electrical characteristics, as well as application information and package drawings. With a publication date of April 2011 and a revised edition in September 2013, the AMC1266 data sheet remains a valuable resource for engineers and designers working with isolation amplifiers.
