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.

LM393N 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

Frequently Asked Questions

1.Is the performance of the integrated circuit LM393N and LM393P the same?
The performance of the integrated circuit LM393N and LM393P are the same. According to the American National Semiconductor Corporation label, the back number belongs to the package label. LM393N is a dual in-line plastic package. The P of LM393P stands for single in-line package.
2.What is the difference between integrated circuit LM393N and LM393P?
If you want to choose LM393N and LM393P, the package form must be DIP-8, except that there is no difference between the manufacturers, other functions are the same.
3.How to use LM393N?Is vcc connected to a 5v power supply? When in(-) is connected to a voltage of 2.5v, is the output 0 power when in(+) is connected to a voltage less than 2.5v?
LM393N is a dual voltage comparator. When (-) is connected to 2.5v voltage, (+) is connected to voltage less than 2.5v and more than 2mV, the output is 0 (low potential). Strictly speaking, it should be that the (+) terminal is lower than the (-) terminal by more than 2mV, the output is 0 (low potential), the (+) terminal is higher than the (-) terminal by more than 2mV, and the output is 1 (high potential).
4.Has the price of LM393N fluctuated a lot recently?
The price of LM393N has not fluctuated much in recent time, the inventory is relatively sufficient, the transaction is relatively frequent, the merchants are very motivated to quote, and the market is high.
5.What integrated block can be used to replace LM393N?
LM393N is a dual-voltage comparator integrated circuit in DIP8 package, which can be directly replaced by integrated circuits such as LM193, LM293, and LM2903.
