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 places the entire device in shutdown mode when held low (IDD = 1.5 nA); the high-level input is 0.9VDD minimum and the low-level input is 0.1VDD maximum. |+| 2 | BYPASS | input | BYPASS is the tap to the voltage divider for internal mid-supply bias and should be connected to a 0.1-µF to 2.2-µF capacitor when used as an audio amplifier. |+| 3 | IN+ | input | IN+ is the noninverting input and is typically tied to the BYPASS terminal for single-ended (SE) input. |+| 4 | IN− | input | IN− is the inverting input and is typically used as the audio input terminal. |+| 5 | VO+ | output | VO+ is the positive bridge-tied load (BTL) audio output. |+| 6 | VDD | power_in | VDD is the supply voltage terminal, with a recommended operating range of 2.5 V to 5.5 V and an absolute maximum of 6 V. |+| 7 | GND | power_in | GND is the ground connection. |+| 8 | VO− | output | VO− is the negative bridge-tied load (BTL) audio output. |+| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | HVSSOP-8-EP |+| Category | Amplifiers/Comparators |+| Pins | 9 |++## CAD (KiCad official)++- Symbol: `TPA751DGNR`+- Footprint: `Package_SO:HVSSOP-8-1EP_3x3mm_P0.65mm_EP1.57x1.89mm`+- 3D model: HVSSOP-8-EP, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.0 mm nominal HVSSOP height).
