Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GAIN | passive | Gain control pin; with pins 1 and 8 open gain is 20 (26 dB), and a capacitor (optionally with series resistor) from pin 1 to pin 8 raises gain up to 200 (46 dB). |
| 2 | -INPUT | input | Inverting input, ground referenced and biased to ground with an internal 50 kΩ resistor. |
| 3 | +INPUT | input | Non-inverting input, ground referenced and biased to ground with an internal 50 kΩ resistor. |
| 4 | GND | power_in | Ground; all voltages are measured with respect to this pin. |
| 5 | VOUT | output | Amplifier output, automatically biased to one half the supply voltage. |
| 6 | VS | power_in | Positive supply; operating range 4V to 12V (LM386-1 types), absolute maximum 15V. |
| 7 | BYPASS | passive | Bypass pin for the internal bias node, decoupled with an external capacitor (10 µF used in PSRR test conditions). |
| 8 | GAIN | passive | Gain control pin; a capacitor from pin 1 to pin 8 bypasses the internal 1.35 kΩ resistor to increase gain up to 200. |
