LMV824MX Equivalent & Substitute Parts

Part Overview

The LMV824MX is a general-purpose operational amplifier featuring four independent circuits in a 14-SOIC surface-mount package. Manufactured by Texas Instruments, this device provides rail-to-rail output capability with a 5.6 MHz gain-bandwidth product and operates across a 2.5 V to 5.5 V supply range. The LMV824MX is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. Substitute parts must maintain functional compatibility through matching circuit count, package type, output configuration, and electrical operating parameters within specified tolerances.
