S-89630A 125C OPERATION, www.ablic.com LOW INPUT OFFSET VOLTAGE CMOS OPERATIONAL AMPLIFIER ABLIC Inc., 2018-2019 Rev.1.0 01 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. Features Low input offset voltage: V = +50 V max. (Ta = 40C to +125C) IO V IO Low input offset voltage drift: = 25 nV/C typ.
