# OPA817DTKR

**Texas Instruments** · Operational Amplifier · WSON-8-EP(3x3)

OPA817DTKR from Texas Instruments, in a WSON-8-EP(3x3). 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 | PD | input | Power down (low = amplifier enabled, high = amplifier disabled); internal 2-MΩ pull-up allows floating this pin |
| 2 | FB | output | Feedback resistor connection (optional) |
| 3 | IN- | input | Inverting input |
| 4 | IN+ | input | Noninverting input |
| 5 | VS- | power_in | Negative power supply |
| 6 | NC | unconnected | No connect (no internal connection to die) |
| 7 | OUT | output | Output of amplifier |
| 8 | VS+ | power_in | Positive power supply |
| 9 | Thermal pad | passive | Electrically isolated from the die substrate. The thermal pad can be connected to any potential between the device power-supplies, but it is recommended to connect it to a heat-spreading plane, typically ground. |

## CAD (KiCad official)

- Symbol: `OPA817DTKR`
- Footprint: `Package_SON:WSON-8-1EP_3x3mm_P0.5mm_EP1.6x2.0mm`
- 3D model: WSON-8-EP(3x3) (KiCad packages3D, STEP)
- 3D model files: `opa817dtkr-etched.step` / `opa817dtkr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa817dtkr.step` / `opa817dtkr.glb` are the bare package body.
