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.
| NO. | NAME | I/O | DESCRIPTION |
|---|---|---|---|
| 1 | 1OUT | O | Output pin of amplifier 1 |
| 2 | 1IN− | I | Inverting input pin of amplifier 1 |
| 3 | 1IN+ | I | Noninverting input pin of amplifier 1 |
| 4 | VCC+ | — | Positive Supply |
| 5 | 2IN+ | I | Noninverting input pin of amplifier 2 |
| 6 | 2IN− | I | Inverting input pin of amplifier 2 |
| 7 | 2OUT | O | Output pin of amplifier 2 |
| 8 | 3OUT | O | Output pin of amplifier 3 |
| 9 | 3IN− | I | Inverting input pin of amplifier 3 |
| 10 | 3IN+ | I | Noninverting input pin of amplifier 3 |
| 11 | VCC− | — | Negative Supply |
| 12 | 4IN+ | I | Noninverting input pin of amplifier 4 |
| 13 | 4IN− | I | Inverting input pin of amplifier 4 |
| 14 | 4OUT | O | Output pin of amplifier 4 |
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.
