Overview
The LMV824DR is a quad low-voltage operational amplifier produced by Texas Instruments. This device is part of the LMV824 series, known for its low input voltage offset and drift, as well as its rail-to-rail output swing. Although the LMV824DR is currently obsolete and no longer in production, it remains a significant component in various legacy systems and designs. It is packaged in a 14-pin SOIC (Small Outline Integrated Circuit) package, making it suitable for a wide range of applications where space is a concern.
