LM393: Dual Comparator
The LM393 is a dual comparator IC manufactured by Texas Instruments, designed for low-power and high-speed signal comparison applications. It is comprised of two independent, high-precision comparators capable of running on one or two power source. The LM393 is typically employed in applications like the detection of voltage levels, zero crossing detectors as well as signal conditioning in a variety of automation and control systems.
Key Features:
- Double Comparator is a package that contains two separate comparators within one package.
- Broad Operating Voltage Band It operates from 2V up to 36V (single supply) or +-1V to +18V (dual supply).
- Open Collector Output allows interaction with different levels of logic and can be used in wired-AND applications.
- Lower Power Consumption is designed to be used in battery-powered, low-power applications..
- low input bias current ensures that there is no effect on input signals.
- Speedy Operation capable to responding to rapidly changing signals with the average propagation delay of 300 nus.
- Hysteresis Capability adjustable hysteresis to ensure stability and noise-proofing even in noisy settings.
- Industrial Temperature Range is able to operate between 40degC up to 125degC to withstand harsh conditions.
- Applications used to create zero-crossing detectors as well as pulse-width modulation (PWM) generation as well as voltage comparator in a variety of systems.
