LM239 Datasheet (STMicroelectronics) - Low-power quad voltage comparators

LM239, Low-power quad voltage comparators

This family of devices consists of four independent precision-voltage comparators with an offset voltage specification as low as 2 mV maximum for LM339A, LM239A, and LM139A.

Each comparator has been designed specifically to operate from a single power supply over a wide range of voltages.

Operation
