TL081CDTR from XBLW, 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 OFFSET N1 input Offset null pin 1. Connect an external trim potentiometer between OFFSET N1 (pin 1) and OFFSET N2 (pin 5) with the wiper tied to VCC- to null the input offset voltage (typ ±3 mV, max ±5 mV).
2 IN- input Inverting input to the JFET-input op-amp. Very high input impedance; input bias current typ ±200 nA (max), input offset current ±100 pA (max). Common-mode range (VCC-)+1.5 V to (VCC+)-0.5 V.
3 IN+ input Non-inverting input to the JFET-input op-amp. Very high input impedance; input voltage range ±15 V absolute max. Common-mode range (VCC-)+1.5 V to (VCC+)-0.5 V.
4 VCC- power_in Negative supply rail. Typically -15 V for a ±15 V split supply; absolute max supply
5 OFFSET N2 input Offset null pin 2. Used with OFFSET N1 (pin 1) and an external potentiometer (wiper to VCC-) to trim the input offset voltage to zero.
6 OUT output Op-amp output. Maximum peak output voltage swing typ ±13.5 V (min ±12 V) with RL = 10 kΩ. Internally short-circuit protected; slew rate typ 20 V/µs (min 8 V/µs), gain-bandwidth typ 3 MHz.
7 VCC+ power_in Positive supply rail. Typically +15 V for a ±15 V split supply; absolute max supply
8 NC unconnected No internal connection. Leave floating or tie to a convenient net; not electrically bonded inside the package.
