LM4901MMX from Texas Instruments, in a VSSOP-10-0.5mm. 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 | Shutdown control input; the device enters shutdown when this pin is in the same logic state as SD Mode, and the pin should be tied to a definite voltage. |
| 2 | Bypass | passive | Half-supply (VDD/2) bypass pin that takes an external capacitor CB (1.0 µF recommended) for filtering and turn-on pop control. |
| 3 | SD Mode | input | Shutdown mode select, tied to VDD for shutdown-high or to GND for shutdown-low operation. |
| 4 | +IN | input | Non-inverting input of the first amplifier. |
| 5 | -IN | input | Inverting input of the first amplifier; the gain is set with Ri and Rf. |
| 6 | Vo1 | output | Bridged-tied-load output 1 from the first amplifier, which drives one side of the speaker. |
| 7 | GND | power_in | Ground pin. |
| 8 | VDD | power_in | Positive supply pin with a 2.0V to 5.5V operating range, to be bypassed with a capacitor placed close to the device. |
| 9 | GND | power_in | Ground pin. |
| 10 | Vo2 | output | Bridged-tied-load output 2 from the second amplifier, which is the inverted copy of Vo1 and drives the other side of the speaker. |
