Overview
The LMV324Q1MAX/NOPB is an automotive-grade, quad operational amplifier (op amp) produced by Texas Instruments. It is a low-voltage version of the traditional LM324 op amp, designed to operate within a voltage range of 2.7 V to 5.5 V. This component is part of the LMV321-N, LMV358-N, and LMV324-N family, which are known for their cost-effectiveness, space efficiency, and low price. These op amps are built using Texas Instruments' advanced submicron silicon-gate BiCMOS process and feature bipolar input and output stages for improved noise performance and higher output current drive.
