THS4121IDGNR

Texas Instruments · Differential Amplifiers · HVSSOP-8-EP

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).

CAD (KiCad official)

  • Symbol: THS4121IDGNR
  • 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). 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: ths4121idgnr-etched.step / ths4121idgnr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ths4121idgnr.step / ths4121idgnr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (37 pp, sha256 705c359dabda7e27, retrieved 2026-10-08, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
