Automotive, 125°C Operation, Low Input Offset Voltage CMOS Operational Amplifier S-19630A

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-19630AB is a dual operational amplifier (2 circuits), which is suitable for applications requiring less offset voltage.

Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the purpose, contact to ABLIC Inc. is indispensable.
