LM193, LM293, LM393 Low power dual voltage comparators Datasheet production data 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 DIP8 of supply voltage (1 mW/comparator at +5 V) (plastic package) Low input bias current: 20 nA typ. Low input offset current: 3 nA typ. Low input offset voltage: 1 mV typ. Input common-mode voltage range includes ground SO-8 (plastic micropackage) Low output saturation voltage: 80 mV typ. (I =4 mA) sink Differential input voltage range equal to the supply voltage TTL, DTL, ECL, MOS, CMOS compatible outputs TSSOP8 (thin shrink small outline package) Available in DIP8, SO-8, TSSOP8, MiniSO-8, and DFN8 2 x 2 mm packages Description MiniSO-8 The LM193, LM293, and LM393 devices consist (plastic micropackage) 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 DFN8 2 x 2 mm voltage range includes ground even though (plastic micropackage) operated from a single power supply voltage.
