Overview
The LM348NSR is a quadruple operational amplifier produced by Texas Instruments. It is designed to have operating characteristics similar to the industry-standard µA741, but with several enhanced features. This device is particularly noted for its low supply-current drain, low input bias and offset currents, and high gain. The LM348NSR is packaged in a 14-pin SOIC (Small Outline Integrated Circuit) package, making it suitable for a variety of applications where space is a concern.
