Overview
The LMV321IDCKT is a single low-voltage operational amplifier produced by Texas Instruments. It is part of the LMV321, LMV358, and LMV324 family, which includes single, dual, and quad operational amplifiers. These devices are designed for low-voltage operation, ranging from 2.7 V to 5.5 V, and are known for their rail-to-rail output swing, making them suitable for applications where space saving and low cost are critical.
The LMV321IDCKT is an upgraded version of the LMV321, offering enhanced performance and reliability. It is packaged in a 5-TSSOP (SC-70-5) package, which is compact and ideal for applications requiring minimal board space.
