LM386L-D08-T from UTC(Unisonic Tech), in a DIP-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 pins 1 and 8 open gain is 20 (26dB), and a capacitor from pin 1 to pin 8 raises gain up to 200 (46dB). |
| 2 | -INPUT | input | Inverting input, ground referenced and biased to ground through 50kΩ, with input voltage limited to -0.4V to +0.4V. |
| 3 | +INPUT | input | Non-inverting input, ground referenced and biased to ground through 50kΩ, with input voltage limited to -0.4V to +0.4V. |
| 4 | GND | power_in | Ground connection. |
| 5 | VOUT | output | Amplifier output that automatically biases to one-half the supply voltage; 250mW typ at VS=6V into 8Ω (THD=10%). |
| 6 | VS | power_in | Supply voltage pin, operating range 4V to 12V with absolute maximum of 15V. |
| 7 | BYPASS | passive | Bypass pin for the internal bias, with a 10μF capacitor used in the supply rejection specification. |
| 8 | GAIN | passive | Gain-setting pin; an external resistor and capacitor between pin 1 and pin 8 increases gain from 20 up to 200. |
