S-19630A CMOS Operational Amplifier ABLIC S-19630A CMOS Operational Amplifier is an automotive, 125°C operation, low input, offset voltage, CMOS operational amplifier in a small package. The zero-drift operational amplifier features Rail-to-Rail input and output and utilizes chopper-stabilizing techniques to deliver low input offset voltage. The ABLIC S-19630AB Amp provides dual operation (2 circuits), which is suitable for applications requiring less offset voltage.
