The LM321LVIDBVR is a single-channel, low voltage operational amplifier (op amp) from Texas Instruments. It is an industry-standard amplifier design with an input voltage range of -40V to 125V. It uses five SOT-23 packages and is capable of driving single-supply applications up to 5.5V. The op amp features low distortion, low noise, and broad bandwidth with excellent stability across a wide temperature range. Its low power consumption and wide supply voltage range make it suitable for many applications, including audio, signal conditioning, and instrumentation. It also provides very high gain bandwidth performance, allowing for fast response times and high-speed signal processing.
