The AD625 is a precision instrumentation amplifier designed for applications requiring nonstandard gains, such as software programmable gain amplifiers (SPGAs). It allows users to set any gain from 1 to 10,000 using an additional three resistors, with gain accuracy primarily determined by these external components. The device is available in various accuracy grades (A, B, C, J, K, S) to suit different temperature ranges, from commercial to extended military specifications.
