STMicroelectronics, Inc. Dual SMD 18V Linear Comparator IC LM2903HD

The LM2903HD is a low power dual voltage comparator designed for operation from a single supply voltage ranging from +2V to +36V or dual supplies of ¬±1V to ¬±18V. It features a very low supply current of 0.4mA, which remains consistent regardless of the supply voltage, making it efficient for battery-operated applications. The device has a low input bias current of 25nA and a low input offset current of ¬±5nA, ensuring accurate performance. The input common-mode voltage range includes ground, allowing for versatile application in various circuits. The output saturation voltage is low at 250mV (typical) when sourcing 4mA, which is beneficial for interfacing with other logic families such as TTL, DTL, ECL, MOS, and CMOS. The LM2903HD is rated for a wide operating temperature range of -40¬8C to +150¬8C, making it suitable for harsh environments. This comparator is packaged in a small outline (SO-8) format, which is advantageous for space-constrained designs. Overall, the LM2903HD is a reliable choice for engineers seeking a low power, versatile comparator for their projects.
