Features
- Low Power Consumption: 1.5mA (Typ) per comparator
- High Speed: 1.3μs (Typ) response time
- Low Offset Voltage: 2mV (Typ)
- Single Supply Operation: 2.7V to 36V
- Dual Comparator: Two independent comparators in one package
- Internal Hysteresis: 5mV (Typ) to prevent oscillations
- Open-Collector Outputs: Compatible with TTL, DTL, and CMOS logic
Applications
- Power Supplies: Overvoltage protection, undervoltage detection
- Data Acquisition Systems: Analog-to-digital conversion, threshold detection
- Industrial Control Systems: Monitoring of temperature, pressure, and flow rate
- Medical Equipment: Patient monitoring, medical imaging
