The difference between LM339AD and LM339N

"LM339AD" and "LM339N" both refer to the same basic model of quad voltage comparator. These comparators are widely used in various electronic applications such as power supply protection, level detection and conversion
Package type: When the product model suffix has "N", it usually indicates a standard plastic package, such as DIP (dual in-line package). Those without "N" may refer to other types of packages or a general term that represents all package types in this series.
LM339 has a wide common mode range, from 0v to power supply voltage -1.5v; the power supply voltage range is wide: single power supply 2-36V; dual power supply voltage is ±1V~±18V.
The LM339N is a quad voltage comparator. It comes in a dual in-line 14-pin package. Maximum operating voltage is ±18V, power consumption is 265mW

LM339 Frequently Asked Questions:


What kind of IC is LM339?

LM339 is a voltage comparator IC of the LMx39x series, which is used in manufacturing in various industries. The device consists of four independent voltage comparators and is designed to operate from a single supply.

What is a comparator IC?

A comparator is an electronic circuit that compares two inputs applied to it and produces an output. The output value of the comparator indicates which input is larger or smaller. It is worth noting that comparators are nonlinear applications of ICs.

How does the LM339 comparator work?

LM339 is a quad op amp comparator. How a comparator works: Each op-amp of a comparator has 2 inputs: an inverting input and a non-inverting input. If the inverting input voltage is greater than the non-inverting input, the output goes to ground.

What is the use of LM339?

The LM339 is used in applications where two voltage signals need to be compared. In addition to the four comparators onboard, the device can compare four pairs of voltage signals at once, which can be useful in certain applications.

Can LM393 replace LM358?

LM358 and LM393 look similar on the surface, but LM358 is a linear output operational amplifier and LM393 is a digital output comparator. Their working principles are different, so they are not interchangeable.
