Overview
The LM2903YPT is a low-power dual voltage comparator produced by STMicroelectronics. This device consists of two independent low-power voltage comparators designed to operate from a single supply over a wide range of voltages, or from split power supplies. It is notable for its wide single supply voltage range of +2 V to +36 V or dual supplies of ±1 V to ±18 V. The LM2903YPT is characterized by its very low supply current, low input bias and offset currents, and compatibility with various logic families such as TTL, DTL, ECL, MOS, and CMOS. This component is also qualified for automotive applications and is available in a TSSOP-8 package.
