Overview
The LMV321IDCKR is a single, low-voltage operational amplifier produced by Texas Instruments. It is part of the LMV321 series, which includes single, dual, and quad operational amplifiers designed for low-voltage operation between 2.7 V and 5.5 V. These devices are known for their cost-effectiveness, space-saving design, and low power consumption, making them ideal for applications where low-voltage operation and compact size are crucial. The LMV321IDCKR is packaged in a SOT-SC70 (DCK) package with 5 pins and operates over a temperature range of –40°C to +125°C.
