Products in this family are used for the reproduction of analog signals with an attendant increase in amplitude, reduction of source impedance, and/or isolation of a signal source from a driven load, as well as performing mathematical operations on analog signals such as summation, negation, integration, etc. Instrumentation amplifiers, chopper stabilized/auto-zero/zero-drift amplifiers, and current feedback types are included.
