This IC incorporates a general purpose analog circuit in a small package. This is a zero-drift operational amplifier with Rail-to-Rail input and output, which uses chopper-stabilizing techniques to provide low input offset voltage.
The S-89630AB is a dual operational amplifier (2 circuits), which is suitable for applications requiring less offset voltage.
