Overview
The LM348DRE4 is a quadruple, independent, high-gain, internally compensated operational amplifier produced by Texas Instruments. This component is part of the LM348 series, which is designed to have operating characteristics similar to the µA741. The LM348DRE4 is known for its low supply-current drain, low input bias and offset currents, and its ability to operate over a temperature range of 0°C to 70°C. It is available in a 14-pin SOIC (Small Outline Integrated Circuit) package, making it suitable for a variety of general-purpose applications in electronic circuits.
