LM4950TS from Texas Instruments, in a TO-263-9. 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 | VINA | input | Channel A audio input; input voltage range is -0.3V to 9.5V. |
| 2 | SHUTDOWN | input | Active-low shutdown input; high threshold is 2.0V min, low threshold is 0.4V max, input range -0.3V to 9.5V. |
| 3 | VOUTA | output | Channel A amplifier output; voltage range is -0.3V to VDD + 0.3V. |
| 4 | GND | power_in | Ground reference for all voltages; supply voltage is referenced to pins 4 and 5. |
| 5 | GND | power_in | Ground reference for all voltages; supply voltage is referenced to pins 4 and 5. |
| 6 | VDD | power_in | Positive supply; operating range 9.6V to 16V, absolute maximum 18.0V referenced to GND. |
| 7 | VOUTB | output | Channel B amplifier output; voltage range is -0.3V to VDD + 0.3V. |
| 8 | BYPASS | passive | Bypass pin for the half-supply reference, with an external capacitor (CB = 10µF used for the 440ms wake-up time); input range -0.3V to 9.5V. |
| 9 | VINB | input | Channel B audio input; input voltage range is -0.3V to 9.5V. |
