PAM8302AADCR

Diodes Incorporated · Audio Power OpAmps · SOP-8

PAM8302AADCR from Diodes Incorporated, 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 SD input Active-low shutdown. Drive low (VSL ≤ 0.4V) to place the amplifier in low-power shutdown (ISHDN ≤ 1µA); drive high (VSH ≥ 1.2V) for normal operation. Recommended to be delayed 1-100ms (typ 10ms) after VDD rises for pop-free start-up.
2 NC unconnected No internal connection. Leave floating or tie to GND for best PCB practice.
3 IN+ input Non-inverting analog audio input. AC-couple through a 0.1-0.22µF capacitor (typ 0.1µF) that forms a high-pass filter with the 10kΩ internal input impedance. Internally biased to VDD/2.
4 IN- input Inverting analog audio input. AC-couple through a 0.1-0.22µF capacitor (typ 0.1µF); for single-ended sources this pin is capacitor-coupled to signal ground. Internal 10kΩ input resistor sets the gain with the 150kΩ feedback resistor (fixed 23.5dB max).
5 VO+ output Positive Class-D BTL PWM speaker output. Connects directly to one speaker terminal (filterless); optional ferrite bead + 220pF to GND for EMI reduction. Delivers up to 2.5W into 4Ω at VDD=5V.
6 VDD power_in Positive supply, 2.0V to 5.5V (absolute max 6.0V). Decouple with a 1µF ceramic close to the pin plus 10µF bulk. Quiescent current typ 4mA, max 8mA at no-load.
7 GND power_in Device ground. All voltages are referenced to this pin; connect to a solid ground plane for best thermal and EMI performance.
8 VO- output Negative Class-D BTL PWM speaker output. Connects directly to the other speaker terminal (filterless); optional ferrite bead + 220pF to GND for EMI reduction.

Two STEP files. Same geometry, different body top:

File Size Use it when
pam8302aadcr.step 122 KB You want the bare part, or you mark your own boards.
pam8302aadcr-etched.step 2.5 MB You want the part with PAM8302AADCR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 625 faces against 147 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.
