Product Summary

The LM393N is a low voltage comparator which is designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. The LM393N 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

LM393N absolute maximum ratings: (1)VCC Supply Voltage: ±18 or 36 V; (2)Vid Differential Input Voltage: ±36 V; (3)Vi Input Voltage: -0.3 to +36 V; (4)Output Short-circuit to Ground - note: Infinite; (5)Pd Power Dissipation: 1250 mW; (6)Rthja: 100℃/W for SO-8 package; (7)Tstg Storage Temperature Range: -65 to +150℃.

Features

LM393N features: (1)Wide single-supply voltage range or dual supplies: +2V to +36V or ±1V to ±18V; (2)Very low supply current (0.4mA) independent of supply voltage (1mW/comparator at +5V); (3)Low input bias current: 25nA typ.; (4)Low input offset current: ±5nA typ.; (5)Low input offset voltage: ±1mV typ.; (6)Input common-mode voltage range includes ground; (7)Low output saturation voltage: 250mV typ. (Io = 4mA); (8)Differential input voltage range equal to the supply voltage; (9)TTL, DTL, ECL, MOS, CMOS compatible outputs.
