Overview
The LMV321ILT, produced by STMicroelectronics, is a low-power, rail-to-rail input/output operational amplifier. It is part of the LMV321/LMV324/LMV358 family, which includes single, dual, and quad operational amplifiers designed for low-cost, general-purpose applications. These op-amps operate with supply voltages as low as 2.7 V and up to 6 V, making them suitable for battery-powered and portable equipment. The LMV321ILT is housed in a space-saving 5-pin SOT23-5 package, simplifying board design and meeting various application requirements.
