Overview
The NCV391SN2T1G is a low-power single voltage comparator designed and manufactured by onsemi. This device is optimized to operate from a single supply over a wide range of voltages, with the capability to also function with split power supplies. A notable feature is its input common-mode voltage range, which includes ground even when operated from a single power supply voltage. This makes it versatile for various applications requiring precise voltage comparison.
