S-19630AB Zero-Drift Dual Amplifier for Automotive Use

ABLIC's S-19630AB is an automotive zero-drift dual amplifier ideal for high-accuracy automotive systems

Image of Ablic's S-19630AB Zero-Drift Dual Amplifier for Automotive Use ABLIC's S-19630AB is a zero-drift operational amplifier with rail-to-rail input and output that uses chopper-stabilizing techniques to provide low input offset voltage. It is a dual operational amplifier (two circuits) suitable for applications requiring less offset voltage and ideal for systems requiring highly accurate current detection, such as linear solenoids.

The S-19630AB has the advantage of a zero-drift amplifier with a wide operating voltage range of 4.0 V to 36 V. Its low offset voltage is approximately 1/100 of that of a bipolar amplifier. The low offset voltage drift (temperature dependency of offset voltage) is approximately 1/10 of an amplifier whose offset voltage has been corrected by trimming and approximately 1/100 of a bipolar amplifier. The S-19630AB's high withstand voltage operation of 36 V and rail-to-rail input enable direct connection to the battery for high-side current detection.
