EG8403 from EG Micro, in a SOP-16. 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 | OUTL+ | output | Left channel non-inverting (positive) Class-D BTL speaker output. Connects to the '+' terminal of the left speaker. |
| 2 | PGND | power_in | Power ground for the left channel Class-D output stage. Tie to the board ground plane close to the decoupling capacitors. |
| 3 | OUTL- | output | Left channel inverting (negative) Class-D BTL speaker output. Connects to the '-' terminal of the left speaker. |
| 4 | PVDD | power_in | Power supply for the Class-D output stage (typical 5V). Decouple locally with a 1µF ceramic (a bulk 470µF is shared across both PVDD pins). |
| 5 | MUTE | input | Mute control input, active low. Drive low to mute the outputs; drive high (or leave floating per typ. app) for normal operation. |
| 6 | VDD | power_in | Analog supply for the internal amplifier front-end and biasing. Decouple with a 1µF ceramic capacitor to GND. |
| 7 | INL | input | Left channel audio input. AC-couple through a series input capacitor (typ. 0.47µF) from the audio source. |
| 8 | VREF | passive | Internal analog reference bypass. Connect a bypass capacitor (typ. 0.1µF) from this pin to GND; do not drive externally. |
| 9 | NC | unconnected | No connect. Leave floating or tie to ground per PCB convenience. |
| 10 | INR | input | Right channel audio input. AC-couple through a series input capacitor (typ. 0.47µF) from the audio source. |
| 11 | GND | power_in | Analog ground return for the front-end and reference circuitry. |
| 12 | SHDN | input | System shutdown control, active low. Drive low to place the device into low-power shutdown; drive high for normal operation. |
| 13 | PVDD | power_in | Power supply for the Class-D output stage (typical 5V). Decouple locally with a 1µF ceramic; shares bulk capacitor with pin 4. |
| 14 | OUTR- | output | Right channel inverting (negative) Class-D BTL speaker output. Connects to the '-' terminal of the right speaker. |
| 15 | PGND | power_in | Power ground for the right channel Class-D output stage. Tie to the board ground plane close to the decoupling capacitors. |
| 16 | OUTR+ | output | Right channel non-inverting (positive) Class-D BTL speaker output. Connects to the '+' terminal of the right speaker. |
