LM193, LM293, LM393 Low-power, dual-voltage comparators Datasheet - production data Description The LM193, LM293, and LM393 devices consist of two independent low voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage. Features Wide single-supply voltage range or dual supplies: 2 V to 36 V or ±1 V to ±18 V Very low supply current (0.45 mA) independent of supply voltage (1 mW/comparator at 5 V) Low input bias current: 20 nA typ. Low input offset current: ±3 nA typ. Low input offset voltage: ±1 mV typ. Input common-mode [ ... ]
