NS4150C from Shenzhen Nsiway Tech, in a SOP-8. 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 | CTRL | input | Operating mode control. Logic high enables the amplifier (Open/Play mode); logic low shuts down the device. VIH ≥ 1.6V @ VDD=5V (1.2V @ VDD=3V); VIL ≤ 0.2V. |
| 2 | Bypass | passive | Internal common-mode voltage bypass capacitor pin. Connect a 1µF ceramic capacitor to GND. Capacitance affects startup time (~165ms @ 5V, ~230ms @ 3V with 1µF). |
| 3 | INP | input | Positive audio input. AC-coupled through Cin and series input resistor Rin; forms a high-pass filter with the internal 240kΩ feedback resistor (gain AVD = 240kΩ/Rin). |
| 4 | INN | input | Negative audio input. AC-coupled through Cin and series input resistor Rin for differential input; tie through Cin/Rin to GND for single-ended input. |
| 5 | VoN | output | Negative Class-D BTL speaker output. Connects to one terminal of the 4Ω or 8Ω speaker load; filterless PWM drive, optional ferrite bead + 1nF for EMI on long wiring. |
| 6 | VCC | power_in | Supply input for the chip and audio output power stage. Recommended operating range 2.2V to 5.0V (absolute max 5.25V). Decouple with 1µF ceramic close to pin, add 10µF for low-frequency filtering. |
| 7 | GND | power_in | Device ground reference. Connect to system ground plane; provides return for supply, bypass capacitor and speaker output currents. |
| 8 | VoP | output | Positive Class-D BTL speaker output. Connects to the other terminal of the speaker load; filterless PWM drive, optional ferrite bead + 1nF for EMI on long wiring. |
