The “B” suffix is used to denote new device variant releases based on an advanced wafer process that provides many device improvements. Maximum supply voltage is increased to 36 V; EMI filters are added to inputs; input offset voltage is reduced (3 mV or 1.8 mV for parts with an ‘A’ in their suffix ); tested low VOL sink drive current is increased (from 12 µA to 50 µA) to support lower resistance feedback networks and more load current; IB maximum decreased (from –250 nA to –35 nA); 2-kV HBM ESD is standard. Most data sheet specifications use a setup of a load terminated to mid-supply to match modern data sheet test conditions.
