Specialized ICs National Semiconductor LM4140BCM Overview
The Specialized ICs National Semiconductor LM4140BCM is a high-precision voltage reference IC, encapsulated in a compact 8-SOIC (0.154, 3.90mm Width) package. This IC is designed to provide a stable 2.5V output with an impressive ±0.1% tolerance, ensuring reliable performance across a variety of applications. It supports a fixed output and is capable of handling a maximum input voltage of 5.6V, with a typical supply voltage of 5V. Its operational temperature range from 0°C to 70°C makes it suitable for a wide range of environmental conditions. The LM4140BCM's low supply current usage of 375µA during operation and 320µA at idle makes it an energy-efficient choice for demanding applications. Notably, it does not contain Substances of Very High Concern (SVHC), making it a safer and more environmentally friendly option for manufacturers.
