Brief introduction of LM393N

Description:

The LM393N 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. This 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 voltage range includes

ground

■ Low output saturation voltage: 80 mV typ.

(Isink = 4 mA)

■ Differential input voltage range equal to the

supply voltage

■ TTL, DTL, ECL, MOS, CMOS compatible

Outputs

Applications: It can be applied to Battery Powered and industrialization.
