Product Summary

The LM393DT is a Low power dual voltage comparator which is a 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. The LM393DT also has a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

Parametrics

LM393DT absolute maximum ratings: (1)Supply voltage:±18V or 36 V; (2)Differential input voltage:±36 V; (3)Input voltage:-0.3 to +36 V; (4)Output short-circuit to ground :Infinite; (5)Thermal resistance junction to ambient:125℃/W; (6)Thermal resistance junction to case:40℃/W; (7)Maximum junction temperature:150℃; (8)Storage temperature range:-65℃ to +150℃; (9)HBM: human body model: 800V; (10) MM: machine mode: 200V; (11) CDM: charged device model: 1500V.

Features

LM393DT features: (1)Wide single-supply voltage range or dual supplies: +2 V to +36 V or ±1 V to ±18 V; (2)Very low supply current (0.4mA) independent of supply voltage (1mW/comparator at +5 V); (3)Low input bias current: 25nA typ.; (4)Low input offset current: ±5nA typ.; (5)Low input offset voltage: ±1 mV typ.; (6)Input common-mode voltage range includes ground; (7)Low output saturation voltage: 250 mV typ. (Isink =4mA); (8)Differential input voltage range equal to the supply voltage; (9)TTL, DTL, ECL, MOS, CMOS compatible outputs.
