Product Introduction

Overview

The LMV324MT, produced by National Semiconductor (now part of Texas Instruments), is a quad general-purpose, low-voltage, rail-to-rail output operational amplifier. This device is part of the LMV321/358/324 family, which offers cost-effective solutions for applications requiring low voltage operation, space savings, and low cost. The LMV324MT operates within a voltage range of 2.7V to 5.5V, making it suitable for battery-powered systems and other low-voltage applications.

These amplifiers are built using National’s advanced submicron silicon-gate BiCMOS process, ensuring excellent speed-power ratio, low supply current, and high output current drive. They are particularly useful in designs where space is limited and signal integrity is crucial.
