The Texas Instruments LMV321IDBVR is a high-performance, single operational amplifier with a wide range of applications. It operates at a single-supply voltage range of 2.7V to 5.5V, making it ideal for battery-powered applications. It has a rail-to-rail output swing, high gain bandwidth product of 1MHz, and a low power consumption. The LMV321IDBVR is packaged in a small SOT-23 package, making it suitable for space-constrained applications. It is robust and can operate from -40°C to 125°C. It is suitable for active filters, general signal conditioning, and amplification.
