TLE2141CDR 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 OFFSET N1 passive Input offset voltage null pin, used with a potentiometer to VCC− (split supply) or GND (single supply) to reduce input offset voltage, and may be left unconnected if nulling is not needed.
2 IN− input Inverting input; inputs operate between VCC− − 0.3 V and VCC+ − 1.8 V without phase reversal.
3 IN+ input Noninverting input; inputs operate between VCC− − 0.3 V and VCC+ − 1.8 V without phase reversal.
4 VCC− power_in Negative supply (split supply) or ground (single supply); total supply range is 4 V to 44 V.
5 OFFSET N2 passive Input offset voltage null pin, used with a potentiometer to VCC− (split supply) or GND (single supply) to reduce input offset voltage, and may be left unconnected if nulling is not needed.
6 OUT output Amplifier output with swing from VCC− + 0.1 V to VCC+ − 1 V under light load, internally current-limited with 20 mA minimum short-circuit current.
7 VCC+ power_in Positive supply; total supply range is 4 V to 44 V.
8 NC unconnected No internal connection.
