TP10-2-SR from UMW, 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 swing within ~5-15 mV of the supply rails at RLOAD=10k. Short-circuit current ~100 mA; drives up to 50 mA at 1V output drop.
2	-INA	input	Inverting input of amplifier A. Rail-to-rail input; common-mode range extends 300 mV beyond V- and V+. Input bias current ~1 pA (25 C).
3	+INA	input	Non-inverting input of amplifier A. Rail-to-rail input; common-mode range (V-)-0.1 V to (V+)+0.1 V. Input bias current ~1 pA (25 C).
4	V-	power_in	Negative supply rail (or GND in single-supply operation). Total supply (V+)-(V-) must be 2.7 V to 5.5 V (7 V absolute max).
5	+INB	input	Non-inverting input of amplifier B. Rail-to-rail input; common-mode range (V-)-0.1 V to (V+)+0.1 V. Input bias current ~1 pA (25 C).
6	-INB	input	Inverting input of amplifier B. Rail-to-rail input; matches +INB common-mode range. Input bias current ~1 pA (25 C).
7	OUTB	output	Amplifier B output. Rail-to-rail swing within ~5-15 mV of the supply rails at RLOAD=10k. Short-circuit current ~100 mA.
8	V+	power_in	Positive supply rail. Single-supply 2.7 V to 5.5 V (or split supply with V-). Absolute max (V+)-(V-)=7 V. Quiescent current ~600 uA per amplifier (1.2 mA total typ).

CAD (KiCad official)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tp10-2-sr.step`	122 KB	You want the bare part, or you mark your own boards.
`tp10-2-sr-etched.step`	1.7 MB	You want the part with `TP10-2-SR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 442 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.
