LM386MX-1 from Texas Instruments, in a SOIC-8-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GAIN | passive | Gain setting pin; connect resistor and capacitor to pin 8 to adjust voltage gain from 20 to 200. |
| 2 | -INPUT | input | Inverting input; 50 kΩ input impedance; 250 nA input bias current. |
| 3 | +INPUT | input | Noninverting input; 50 kΩ input impedance; 250 nA input bias current. |
| 4 | GND | power_in | Ground reference. |
| 5 | VOUT | output | Audio output; output biased to approximately VS/2; can drive 4 Ω to 32 Ω loads. |
| 6 | VS | power_in | Power supply voltage; operating range 4 V to 12 V; bypass to ground recommended. |
| 7 | BYPASS | output | Bypass decoupling path; connect capacitor to ground for ripple reduction. |
| 8 | GAIN | passive | Gain setting pin; connect resistor and capacitor to pin 1 to adjust voltage gain from 20 to 200. |
