LM393 Dual Voltage Comparator Specifications
The LM393 is a commonly used integrated circuit (IC) containing two independent precision voltage comparators. 
 
Parameter
Specification
Type
Dual Voltage Comparator
Function
Compares two analog voltage inputs and provides a digital output indicating which voltage is higher.
Input Voltage Range
Wide range, typically from a minimum of around 2 volts up to 36 volts (depending on supply voltage).
Output Type
Open-drain output
* Can sink current when the output is low. * Requires external pull-up resistor for logic-level operation.
| Input Offset Voltage | Low offset voltage (typically in the millivolt range), minimizing errors in comparisons. | | Supply Voltage | Wide operating range, typically from 2V to 36V. | | Power Consumption | Low current consumption (around 200 µA per comparator). | | Package | Typically DIP-8 or SOIC-8 |
Additional Notes:
The LM393 is a versatile comparator IC used in various applications requiring voltage level detection or comparison, such as:
Window comparators (detecting voltages within a specific range)
Zero-crossing detection for AC signals
Threshold detection in logic circuits
Signal conditioning circuits
The open-drain output allows for flexible connection to different logic levels.
