Overview
The LMV324MTX/NOPB is a 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 power consumption. The LMV324-N is particularly suited for applications where low-voltage operation and compact design are crucial.
The device is built using Texas Instruments' advanced submicron silicon-gate BiCMOS process, which enhances noise performance and output current drive. It features bipolar input and output stages, ensuring excellent speed to power ratio with a gain-bandwidth product of 1 MHz and a slew rate of 1 V/µs.
