Overview
The LM2903HYPT is a low-power dual voltage comparator manufactured by STMicroelectronics. This device is designed to operate from a single supply over a wide range of voltages, from 2 V to 36 V, or from dual supplies ranging from ±1 V to ±18 V. It features two independent comparators, making it versatile for various applications requiring voltage comparison.
The LM2903HYPT is notable for its very low supply current of 0.4 mA, which is independent of the supply voltage, and its compatibility with multiple logic families including TTL, DTL, ECL, MOS, and CMOS. This makes it an efficient and adaptable component for a variety of electronic systems.
