2903Y Datasheet Low-power dual voltage comparator

Manufacturer: STMicroelectronics

General Description

This device consists of two independent lowpower voltage comparators designed specifically to operate from a single supply over a wide range of voltages.

Operation from split power supplies is also possible.

In addition, the device has a unique characteristic in that the input common-mode voltage range includes the negative rail even though operated from a single power supply voltage.
