LM386M-1 from Texas Instruments, in a SOIC-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; with a resistor and capacitor connected between pins 1 and 8 the gain can be set from 20 to 200, and with pins 1 and 8 open the internal gain is 20. |
| 2 | -INPUT | input | Inverting input of the amplifier. |
| 3 | +INPUT | input | Noninverting input of the amplifier. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | VOUT | output | Amplifier output. |
| 6 | VS | power_in | Power supply voltage pin; the datasheet specifies 4 V to 12 V for LM386M-1 (Recommended Operating Conditions, page 4). |
| 7 | BYPASS | output | Bypass decoupling path, used to decouple the internal bias node with an external capacitor. |
| 8 | GAIN | passive | Gain setting pin; used together with pin 1 to connect an external resistor and capacitor for gain setting between 20 and 200. |
