The LM393 is a dual independent voltage comparator IC designed to operate from a single power supply over a wide voltage range. It provides low offset voltage and low power consumption, making it ideal for battery-operated and portable applications. The outputs of the LM393 can be connected to other open-collector outputs to achieve wired-AND functionality.
This IC is widely used in analog-to-digital conversion, zero-crossing detectors, and voltage level detectors. Its DIP-8 through-hole package ensures ease of prototyping and integration into standard circuit boards.
Features of LM393 Comparator IC:
- Dual independent precision voltage comparators
- Low input offset voltage: typically 2 mV
- Wide single or dual supply voltage range: 2V to 36V (single supply)
- Low supply current: 0.4mA per comparator (typical)
- Output compatible with TTL and CMOS logic levels
- Open collector output for wired-AND connections
- High input impedance
- DIP-8 package for easy mounting and soldering
