LM393 datasheet

Description

The LM2903, LM393, LM393A, LM293A consist of two independent voltage comparators designed to operate from a single power supply over a wide voltage range.

The LM393 series are dual independent precision voltage comparators capable of single or split supply operation. These devices are designed to permit a common mode range–to–ground level with single supply operation.

Input offset voltage specifications as low as 2.0 mV make this device an excellent selection for many applications in consumer automotive, and industrial electronics

Features

• Single Supply Operation : 2V to 36V

• Dual Supply Operation : ±1V to ±18V

• Allow Comparison of Voltages Near Ground Potential

• Low Current Drain 800μA Typ.

• Compatible with all Forms of Logic

• Low Input Bias Current 25nA Typ.

• Low Input Offset Current ±5nA Typ.

• Low Offset Voltage ±1mV Typ.

Applications:

1. Vacuum robot

2. Single phase UPS

3. Server PSU

4. Cordless power tool

5. Wireless infrastructure

AP393A datasheet

 

Description

The AP393A consists of two independent precision voltage comparators with an offset voltage specification as low as 8.0mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These 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.

Application areas include limit comparators, simple analog to digital converters; pulse, square wave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The AP393A is designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the AP393A will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.

Features

1. Wide supply Voltage range : 2.0V to 36V, Single or dual supplies: ±1.0V to ±18V

2. Very low supply current drain (0.4mA) – independent of supply voltage

3. Low input biasing current: 150nA

4. Low input offset current: ±70nA

5. Low input offset voltage: ±4mV

6. Input common-mode voltage range includes ground

7. Differential input voltage range equal to the power supply voltage

8. Low output saturation voltage: 250mV at 4mA

9. Output voltage compatible with TTL, DTL, ECL, MOS and CMOS logic systems

 

Applications:

1. High precision comparators

2. Reduced VOS drift over temperature

3. Eliminates need for dual supplies

4. Allows sensing near ground

5. Compatible with all forms of logic

6. Power drain suitable for battery operation
