Description
CD2903 is a dual channel comparator whose output can be connected to other open collector outputs to realize line and logic. It can operate between 2V and 30V, and the power consumption of each channel (typical value) is as low as μA level. The CD2903 consists of two independent voltage comparators designed to operate from a single power supply over a wide voltage range. Quiescent current has nothing to do with power supply voltage. For the application of low input offset voltage, high power supply voltage, low power supply current and space saving are the main technical indicators of portable consumer goods circuit design, this device is the most cost-effective solution.
