LM384N from Texas Instruments, in a PDIP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BYPASS | passive | Bypass pin for the internal bias, decoupled to ground with a 5 µF capacitor in the typical application. |
| 2 | NON-INVERTING INPUT | input | Non-inverting input, ground-referenced; tied to ground in the typical 5W amplifier, with input voltage limited to ±0.5V. |
| 3 | GND | power_in | Ground pin that is part of the heat sink pins (3, 4, 5) of the copper lead frame. |
| 4 | GND | power_in | Ground pin that is part of the heat sink pins (3, 4, 5) of the copper lead frame. |
| 5 | GND | power_in | Ground pin that is part of the heat sink pins (3, 4, 5) of the copper lead frame. |
| 6 | INVERTING INPUT | input | Inverting input, which receives the signal in the typical 5W amplifier, with input voltage limited to ±0.5V and input impedance of 150 kΩ. |
| 7 | GND | power_in | Ground pin for the amplifier. |
| 8 | VOUT | output | Amplifier output, self-centering to one-half the supply voltage, short-circuit proof with peak current capability of 1.3A. |
| 9 | NC | unconnected | No connection. |
| 10 | GND | power_in | Ground pin that is part of the heat sink pins (10, 11, 12) of the copper lead frame. |
| 11 | GND | power_in | Ground pin that is part of the heat sink pins (10, 11, 12) of the copper lead frame. |
| 12 | GND | power_in | Ground pin that is part of the heat sink pins (10, 11, 12) of the copper lead frame. |
| 13 | NC | unconnected | No connection. |
| 14 | VS | power_in | Positive supply voltage, 12V to 26V operating range, 28V absolute maximum. |
