ABLIC Inc. Launches the S-19630AB, a Zero-drift Operational Amplifier for Automotive Use with a Wide Operation Voltage Range


ABLIC Inc. (hereinafter “ABLIC”), a semiconductor manufacturer, today launched the S-19630AB, a zero-drift operational amplifier for automotive use.

A zero-drift operational amplifier monitors its offset voltage at all times to automatically adjust it to zero.

The new S-19630AB product is an operational amplifier for automotive use featuring a wide operation voltage range (4.0V to 36V), low offset voltage of 50μV max., low offset voltage drift of 25nV/°C, current consumption of 250μA and is capable of operating at 125°C.

By employing an offset canceling circuit provided by our unique chopper-stabilizing techniques, the S-19630AB achieves excellent low-offset voltage characteristics. The S-19630AB also complies with both the AEC-Q100 automotive IC quality standard and the “Production Part Approval Process” (PPAP) established by the Automotive Industry Action Group (AIAG).

Major Features

  1. A wide operation voltage range
  2. High-accuracy due to low offset voltage and low offset voltage drift
  3. Rail-to-Rail input and output operation
  4. Ensures quality of automotive equipment

Application Examples

  • High-accuracy current detection
  • Multi-sensor interface
  • Strain gauge amplifier
