LMC6492BEMX/NAK1 Equivalent & Substitute Parts

Part Overview

The LMC6492BEMX/NAK1 is a CMOS operational amplifier featuring two independent circuits with rail-to-rail output capability in an 8-SOIC surface mount package. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The part is designed for applications requiring low input bias current, low input offset voltage, and operation across a wide supply voltage range from 2.5V to 15.5V.

Due to its Last Time Buy status, identifying equivalent substitute parts is essential for design continuity and long-term component availability. The substitute part maintains identical electrical performance characteristics while offering active product status and improved supply chain accessibility.
