# OPA1633DGNR

**Texas Instruments** · Audio Amplifiers · HVSSOP-8

OPA1633DGNR from Texas Instruments, in a HVSSOP-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 | IN- | input | Negative input voltage pin. |
| 2 | VOCM | input | Output common-mode control voltage pin. |
| 3 | V+ | power_in | Positive supply voltage pin; recommended operation is dual ±2 V to ±17.5 V or single 4 V to 35 V. |
| 4 | OUT+ | output | Positive output voltage pin. |
| 5 | OUT- | output | Negative output voltage pin. |
| 6 | V- | power_in | Negative supply voltage pin; recommended operation is dual ±2 V to ±17.5 V or single 4 V to 35 V. |
| 7 | Enable | input | Active-high enable pin. |
| 8 | IN+ | input | Positive input voltage pin. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `OPA1633DGNR`
- Footprint: `Package_SO:HVSSOP-8-1EP_3x3mm_P0.65mm_EP1.57x1.89mm`
- 3D model: HVSSOP-8, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.0 mm nominal HVSSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `opa1633dgnr-etched.step` / `opa1633dgnr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa1633dgnr.step` / `opa1633dgnr.glb` are the bare package body.
