- 🔎 High sensitivity for precise threshold detection
- 🧩 Ideal for sensor triggering, zero-crossing, level detection
- 🚪 Open-collector outputs—easy pull-up for logic interfacing
- 📡 Works well with 3.3V/5V microcontrollers and TTL/CMOS
- 🛠️ Simple to build Schmitt triggers and window comparators
- 📦 Common DIP/SMD package options for prototyping/production
LM393 Dual Differential Comparator
8,00 EGP- ⚖️ Dual differential comparator (2 channels) in one IC
- ⚡ Wide operating voltage for flexible power designs
- 🔎 Accurate threshold detection for analog signals
- 🚪 Open-collector outputs—easy pull-up to 3.3V/5V logic
- 🧩 Perfect for sensor modules, level/over-voltage detection
- ⚡ Fast response for pulse and edge detection circuits
- 🛠️ Great for building Schmitt triggers and window comparators
- 📦 Easy to use in breadboard prototypes and embedded projects
A comparator IC continuously compares two input voltages and switches its output between two states depending on which input is higher - the core building block behind threshold alarms, zero-crossing detectors, and converting a noisy analog signal into a clean digital on/off signal.
