Texas Instruments · Audio Amplifiers · WSON-10-EP(4x4)
LM4951ASD from Texas Instruments, in a WSON-10-EP(4x4). 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 | Bypass | output | Half-supply reference voltage bypass output for power supply bypassing. |
| 2 | Shutdown | input | Active-low shutdown control signal; pulling low enters shutdown mode. |
| 3 | CCHG | output | Capacitor charge output to decrease turn-on time. |
| 4 | NC | unconnected | No connection to die; pin can be connected to any potential. |
| 5 | VIN | power_in | Single-ended signal input pin. |
| 6 | VO- | output | Inverting output of amplifier. |
| 7 | GND | power_in | Ground connection. |
| 8 | NC | unconnected | No connection to die; pin can be connected to any potential. |
| 9 | VDD | power_in | Power supply input. |
| 10 | VO+ | output | Non-inverting output of amplifier. |
| 11 | Exposed DAP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
