PAM8303DBSC from Diodes Incorporated, in a MSOP-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 | OUT+ | output | Positive BTL (bridge-tied load) Class-D switching output. Drives one terminal of the speaker via an optional ferrite-bead EMI filter. High-side PMOS / low-side NMOS output stage; RDS(on) ~365 mΩ typ at VDD=5V (MSOP/DFN). |
| 2 | PVDD | power_in | Power supply for the H-bridge output stage. Recommended operating range 2.8V to 5.5V (abs max 6.0V). Decouple with 1µF ceramic close to the pin plus a 10µF bulk cap; keep separate from analog VDD trace. |
| 3 | VDD | power_in | Analog power supply for the input amplifier, bias and reference. 2.8V to 5.5V operating; decouple with 1µF ceramic close to the pin. Route separately from PVDD back to the supply. |
| 4 | IN- | input | Negative differential audio input. AC-coupled through an input capacitor Ci and gain-setting resistor Ri; internal 150 kΩ feedback sets Gain = 2 × 150 kΩ / Ri (V/V). Input biased to VDD/2 internally. |
| 5 | IN+ | input | Positive differential audio input. AC-coupled through Ci and Ri; for single-ended sources the unused input is AC-grounded through Ci. Input biased to VDD/2 internally. |
| 6 | SD | input | Active-low shutdown terminal. Drive low (VIL ≤ 0.3V at VDD=5V) to place the device in shutdown (ISD ≈ 0.5µA typ); drive high (VIH ≥ 1.5V at VDD=5V) for normal operation. Do not leave floating. |
| 7 | GND | power_in | Device ground reference. Tie signal-ground return of input components to this pin, then to system ground; keep separated from power-stage ground return per layout guidelines. |
| 8 | OUT- | output | Negative BTL Class-D switching output. Drives the opposite speaker terminal from OUT+ (180° out of phase). Use an optional ferrite-bead + capacitor EMI filter for radiated emissions. |
