THS4281DR from Texas Instruments, in a SOIC-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 | NC | unconnected | No internal connection; this pin is not connected to the die. |
| 2 | IN- | input | Negative (inverting) input voltage pin; the common-mode input range extends 400 mV beyond the supply rails. |
| 3 | IN+ | input | Positive (non-inverting) input voltage pin; the common-mode input range extends 400 mV beyond the supply rails. |
| 4 | VS- | power_in | Negative supply voltage pin; tie to GND for single-supply operation (dual supply ±1.35 V to ±8.25 V, single supply 2.7 V to 16.5 V per Section 6.3). |
| 5 | NC | unconnected | No internal connection; this pin is not connected to the die. |
| 6 | VOUT | output | Amplifier output voltage pin; the output swings to within 150 mV of the rails with 1-kΩ loads. |
| 7 | VS+ | power_in | Positive supply voltage pin; absolute maximum supply voltage VS- to VS+ is 16.5 V. |
| 8 | NC | unconnected | No internal connection; this pin is not connected to the die. |
