ns4160.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 8 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

NS4160

Shenzhen Nsiway Tech · Audio Power OpAmps · ESOP-8

NS4160 from Shenzhen Nsiway Tech, in a ESOP-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 Shutdown and Class-AB/Class-D mode selection control input via a one-wire pulse protocol. Logic low shuts down the amplifier (Vctrl=VDD puts the chip in shutdown with ~1 µA typical leakage). VIH ≥ 1.4V, VIL ≤ 0.4V; one-wire pulse high/low time 1-12 µs, shutdown assertion time ≥ 100 µs.
2 Bypass passive Internal reference-voltage bypass node. Connect an external decoupling capacitor (typ. 0.1 µF) from this pin to GND to filter the mid-supply reference and improve PSRR/noise performance.
3 INP input Positive (non-inverting) differential audio input to the input buffer. AC-coupled through a 0.1 µF capacitor with a 10 kΩ series/gain-setting resistor in the typical application.
4 INN input Negative (inverting) differential audio input to the input buffer. AC-coupled through a 0.1 µF capacitor with a 10 kΩ series/gain-setting resistor in the typical application.
5 VoN output Negative bridge-tied-load (BTL) speaker output from the output stage. Drives one terminal of the loudspeaker directly (filterless in Class-D mode); supports 2Ω/4Ω/8Ω loads.
6 VDD power_in Positive power supply input, 3.0 V to 5.5 V (absolute max 5.5 V). Decouple to GND with a 1 µF capacitor close to the pin. Typical quiescent current IDD ≈ 12 mA at 3.6 V and 18 mA at 5.0 V.
7 GND power_in Device ground return. Provides the reference for the supply, bypass capacitor, and speaker return currents; also acts as the thermal reference for the eSOP-8 package.
8 VoP output Positive bridge-tied-load (BTL) speaker output from the output stage. Drives the other terminal of the loudspeaker directly (filterless in Class-D mode); supports 2Ω/4Ω/8Ω loads.

CAD (KiCad official)

  • Symbol: NS4160
  • Footprint: Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.41x3.3mm
  • 3D model: ESOP-8 (KiCad packages3D, STEP)
  • 3D model files: ns4160-etched.step / ns4160-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ns4160.step / ns4160.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ns4160.step 193 KB You want the bare part, or you mark your own boards.
ns4160-etched.step 1.2 MB You want the part with NS4160 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 311 faces against 63 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
