Product Attributes
Description

Utilizing the circuit designs perfected for recently introduced Quad Operational  Amplifiers, these dual operational amplifiers feature

1）low power drain

2）a common mode input voltage range extending to ground/VEE

3）single supply or split supply operation and

4）pinouts compatible with the popular MC1558 dual operational amplifier. 

The LM158 series is equivalent to one–half of an LM124.

Features 

● Short Circuit Protected Outputs

● True Differential Input Stage

● Single Supply Operation: 3.0 V to 32 V

● Low Input Bias Currents

● Internally Compensated

● Common Mode Range Extends to Negative Supply

Product Attributes
Not found, similar datasheet recommended

Description

Voltage comparators are the circuits which are used to compare the two input voltage signals and then produce output in digital form which will be either one or zero depending upon the magnitude of the voltage applied to the inputs. Output will be zero or low if the voltage applied to negative terminal of the comparator are higher than the positive terminal and output will be one or high if the voltage at the positive terminal of the comparator are higher than the negative terminal.

LM339N is Quad voltage comparator, which means this single IC chip has four independent voltage comparator circuits and all the comparators can be operated using single power supply. IC LM339N can handle a wide range of input supply voltage ranging from 2V to 36 V. However, operation from dual supply is also possible.

Features

●   Low input biasing current 25nA

●   Low input offset current ±5nA and offset voltage

●   Input common–mode voltage range includes ground

●   Differential input voltage range equal to the power supply voltage

●   Low output 250mV at 4mA saturation voltage
