LM393N Dual Comparator
The LM393N is a dual independent precision voltage comparator designed to operate from a single power supply over a wide voltage range. It compares two voltages and provides a digital output to indicate which is higher. The open-collector output allows for wired-AND configurations.
Specifications:
- Dual independent comparators
- Supply Voltage Range: 2V to 36V (single supply) or ±1V to ±18V (dual supply)
- Input Offset Voltage: Typically 2 mV
- Input Bias Current: Typically 25 nA
- Low Output Saturation Voltage: 250 mV at 4 mA
- Open-collector output for wired logic connection
- Power Consumption: Low (typical standby current ~0.4 mA)
- Operating Temperature Range: 0°C to +70°C (commercial)
- Package: 8-pin DIP (LM393N)
Applications:
- Voltage level detection
- Zero-crossing detectors
- Oscillator circuits
- Analog-to-digital interface
- Battery monitoring circuits
- Overvoltage protection systems
