LM380N-8 from Texas Instruments, in a PDIP-8. 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 | NC | unconnected | No connection on the 8-pin PDIP (P package). |
| 2 | NON-INVERTING INPUT | input | Non-inverting input; ground-referenced input stage with 150kΩ typical input resistance and ±0.5V maximum input voltage. |
| 3 | INVERTING INPUT | input | Inverting input; ground-referenced input stage with 150kΩ typical input resistance and ±0.5V maximum input voltage. |
| 4 | GND | power_in | Ground pin; together with pin 5 it forms the heat sink path on the 8-pin package. |
| 5 | GND | power_in | Ground pin; together with pin 4 it forms the heat sink path on the 8-pin package. |
| 6 | VOUT | output | Amplifier output, short-circuit proof with internal thermal limiting, 1.3A peak current, self-centers to one-half the supply voltage. |
| 7 | VS | power_in | Positive supply, 10V to 22V operating range with 22V absolute maximum. |
| 8 | BYPASS | passive | Bypass pin for an external capacitor; datasheet specifies CBYPASS = 0.47µF for THD and 5µF for PSRR measurements. |
