The new datasheet increases the recommended maximum junction temperature from 125°C to 140°C (absolute maximum 150°C), allowing higher ambient operation for industrial sensors. 3. Pin Configuration (New Revision Changes) One of the most frequent complaints about the PAN186CV older versions was a confusing pin assignment in SOP-8 packages. The new datasheet clarifies: Download the official new datasheet, simulate with your
