# THS4051CDGNR

**Texas Instruments** · Operational Amplifier · HVSSOP-8-EP

THS4051CDGNR 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 | NULL | passive | Offset-null terminal of the THS4051, used with an external null network as shown in the evaluation board schematic (Figure 58). |
| 2 | IN− | input | Inverting input; the absolute maximum input voltage is ±VCC and the differential input voltage limit is ±4 V. |
| 3 | IN+ | input | Noninverting input; the absolute maximum input voltage is ±VCC and the differential input voltage limit is ±4 V. |
| 4 | VCC− | power_in | Negative supply rail; recommended supply is ±4.5 V to ±16 V dual or 9 V to 32 V single, with absolute maximum ±16.5 V. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Amplifier output, rated at 150 mA absolute maximum output current with 100 mA typical drive capability. |
| 7 | VCC+ | power_in | Positive supply rail; recommended supply is ±4.5 V to ±16 V dual or 9 V to 32 V single, with absolute maximum ±16.5 V. |
| 8 | NULL | passive | Offset-null terminal of the THS4051, used with an external null network as shown in the evaluation board schematic (Figure 58). |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `THS4051CDGNR`
- 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: `ths4051cdgnr-etched.step` / `ths4051cdgnr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ths4051cdgnr.step` / `ths4051cdgnr.glb` are the bare package body.
