THS4121IDGNR from Texas Instruments, in a HVSSOP-8-EP. 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 | VIN− | power_in | Inverting input of the fully differential amplifier; input voltage is limited to ±VDD. |
| 2 | VOCM | input | Output common-mode voltage control input of the fully differential amplifier. |
| 3 | VDD | power_in | Positive supply, nominal 3.3 V with an absolute maximum of 3.6 V from GND to VDD. |
| 4 | VOUT+ | output | Non-inverting differential output, with output sink current limited to 110 mA absolute maximum. |
| 5 | VOUT− | output | Inverting differential output, with output sink current limited to 110 mA absolute maximum. |
| 6 | GND | power_in | Ground (negative supply) reference for the device. |
| 7 | NC | unconnected | No internal connection on the THS4121 (this pin is PD on the THS4120). |
| 8 | VIN+ | power_in | Non-inverting input of the fully differential amplifier; input voltage is limited to ±VDD. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
