LM4876MX from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SHUTDOWN | input | Active-low micro-power shutdown input; shutdown is activated below 400mV (VIL 0.4V max, VIH 1.2V min) and should be tied to ground for lowest shutdown current. |
| 2 | BYPASS | passive | Half-supply bypass node; a 1µF capacitor to ground improves PSRR and sets turn-on settling for click and pop performance. |
| 3 | +IN | input | Non-inverting input of Amp1. |
| 4 | -IN | input | Inverting input of Amp1, connected through Ri and Ci to the signal with Rf feedback setting gain AVD = 2*(Rf/Ri). |
| 5 | Vo1 | output | Amp1 output, one side of the bridge-tied load. |
| 6 | VDD | power_in | Positive supply, 2.0V to 5.5V operating range (6.0V absolute max), bypassed locally with a capacitor to ground. |
| 7 | GND | power_in | Ground. |
| 8 | Vo2 | output | Amp2 output (gain of -1 from Amp1), the other side of the bridge-tied load. |
