LF347N Pinout
The LF347N is a high-speed JFET-input operational amplifier IC, widely used in analog signal processing applications. It contains four independent op-amps in a 14-pin dual in-line package (DIP), offering high slew rate, low input bias current, and low noise. Each op-amp has its dedicated inverting input (IN−), non-inverting input (IN+), and output (OUT), making it ideal for multi-channel signal amplification. The pinout diagram ensures easy identification of each functional pin for precise circuit design and implementation.

With its clearly defined pin configuration, the LF347N simplifies the integration of multiple op-amps in compact designs. Its standard 14-pin DIP layout supports straightforward PCB routing and prototyping. Understanding the pinout is crucial for proper power supply connection (V_CC+ at Pin 4 and V_CC− at Pin 11) and accurate signal input/output handling, making the LF347N a reliable choice in both commercial and educational analog circuit applications.
