LM4906MM from Texas Instruments, in a VSSOP-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-high enable input: pulling it high turns the part on and pulling it low/ground puts it in shutdown (0.1µA typ), and it should be tied to a definite voltage. |
| 2 | GND | power_in | Ground pin, tied to the internal bias and shutdown circuitry. |
| 3 | Gain Select | input | Gain select input that sets the gain to 6dB when low and 12dB when high. |
| 4 | IN- | input | Audio input through a 20kΩ input resistor, coupled via an input capacitor (C2 0.39µF in the reference design). |
| 5 | Vo1 | output | First bridged amplifier output (negative side of the BTL load), biased at half supply. |
| 6 | VDD | power_in | Positive supply, 2.6V to 5.5V operating range, bypassed with a 1µF capacitor placed close to the device. |
| 7 | GND | power_in | Ground pin, connected together with pin 2 to ground. |
| 8 | Vo2 | output | Second bridged amplifier output (positive side of the BTL load), 180° out of phase with Vo1. |
