LM393 is a voltage comparator from Dinghao Electronics. It has wide supply voltage range, low supply current, low input biasing current, low input offset current, low input offset voltage, input common-mode voltage range includes GND, differential input voltage range etc.
The LM393 contains two independent voltage comparators designed for single‑supply operation from 5 V to 30 V. It features low supply‑current drain, low input bias and offset currents, and output stages compatible with TTL, MOS and CMOS logic.
Typical applications include TTL and CMOS driving, basic comparator circuits, pulse generation, and crystal‑controlled oscillators. Ordering information and package options (DIP‑8, SOP‑8) are provided for easy integration.
