TPH2502-SR from 3PEAK, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OutA | output | Amplifier A output. Rail-to-rail output stage, capable of >100mA output current, short-circuit current 160mA sink / 290mA source typical, output swing to within 2mV of supply rails (RLOAD=100kΩ). |
| 2 | -InA | input | Amplifier A inverting input. Rail-to-rail input range (V- to V+), input bias current 0.3pA typ at 27°C, differential input impedance 10^13Ω |
| 3 | +InA | input | Amplifier A non-inverting input. Rail-to-rail input range (V- to V+), input bias current 0.3pA typ at 27°C, common-mode input voltage range V--0.1 to V+-0.1V. |
| 4 | -Vs | power_in | Negative supply rail (V-). Typically ground in single-supply operation, or the negative rail in dual-supply configuration. Total supply (V+ - V-) range 2.5V to 5.5V, absolute max 7.0V. Bypass close to pin. |
| 5 | +InB | input | Amplifier B non-inverting input. Rail-to-rail input range (V- to V+), input bias current 0.3pA typ at 27°C, common-mode input voltage range V--0.1 to V+-0.1V. |
| 6 | -InB | input | Amplifier B inverting input. Rail-to-rail input range (V- to V+), input bias current 0.3pA typ at 27°C, differential input impedance 10^13Ω |
| 7 | OutB | output | Amplifier B output. Rail-to-rail output stage, capable of >100mA output current, short-circuit current 160mA sink / 290mA source typical, output swing to within 2mV of supply rails (RLOAD=100kΩ). |
| 8 | +Vs | power_in | Positive supply rail (V+). Supply range 2.5V to 5.5V (with respect to V-), absolute max 7.0V. Quiescent current 6.5mA typ per amplifier (13mA total for dual). Bypass with 0.1µF ceramic close to pin. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 525 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
