Overview
The LMV321Q1M5X/NOPB, produced by Texas Instruments, is an automotive-grade, single-channel operational amplifier designed for low-voltage applications. It is part of the LMV321-N, LMV358-N, and LMV324-N family, which are low-voltage versions of the traditional LM321, LM358, and LM324 op-amps. These devices are built using Texas Instruments' advanced submicron silicon-gate BiCMOS process, ensuring high performance and efficiency.
This op-amp is particularly suited for applications where low-voltage operation, space efficiency, and cost-effectiveness are crucial. It offers rail-to-rail output swing, includes ground in the input common-mode voltage range, and exhibits excellent speed-to-power ratio with a gain-bandwidth product of 1 MHz and a slew rate of 1 V/µs.
