COSINE LM393SR

The LM393 (dual) and LM339 (quad) are low-power, low offset voltage differential comparators operated on 2V to 36V single supply or ±1V to ±18V dual supplies. Despite their wide supply range, the LM393/339 family provides excellent overall performance and versatility. They have high differential input voltage capability. The common-mode input voltage range includes ground, enabling direct sensing near ground. The output current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships. Input offset voltage as low as 2mV make this device family an excellent selection for many applications in consumer, automotive, and industrial electronics.
