LM386N-3 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 | GAIN | passive | Gain setting pin connected with external resistor and capacitor between pins 1 and 8 to configure gain from 20 to 200. |
| 2 | -INPUT | input | Inverting input receiving analog signal with voltage range -0.4 V to +0.4 V with respect to ground. |
| 3 | +INPUT | input | Noninverting input receiving analog signal with voltage range -0.4 V to +0.4 V with respect to ground. |
| 4 | GND | power_in | Ground reference for input bias and output signal return path. |
| 5 | VOUT | output | Output driving speaker loads with impedance from 4 Ω to 32 Ω. |
| 6 | VS | power_in | Power supply voltage pin operating at 4 V to 12 V for LM386N-3. |
| 7 | BYPASS | output | Bypass capacitor connection for frequency compensation and output decoupling. |
| 8 | GAIN | passive | Gain setting pin connected with external resistor and capacitor between pins 8 and 1 to configure gain from 20 to 200. |
