4558 from PUOLOP, 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 OUT1 output Output of op-amp channel 1. Output voltage swing up to Vcc-1.5 V; source current typ -120 mA, sink current typ 120 mA under Vo=2 V test conditions.
2 IN1(-) input Inverting input of op-amp channel 1. Input offset voltage typ 2 mV (max 6.0 mV), input bias current typ 30 nA. Absolute max input voltage ±15 V, differential ±16 V.
3 IN1(+) input Non-inverting input of op-amp channel 1. Common-mode input voltage range typ ±12 V (max ±13 V) with Vcc=15 V, Vee=-15 V. CMRR typ 90 dB.
4 Vee power_in Negative supply rail (or GND for single-supply operation). Absolute maximum supply voltage ±20 V. Typical quiescent supply current 3.5 mA (max 5.7 mA) at Vcc=15 V, Vee=-15 V.
5 IN2(+) input Non-inverting input of op-amp channel 2. Common-mode input voltage range typ ±12 V (max ±13 V). Low input bias current (~30 nA typ).
6 IN2(-) input Inverting input of op-amp channel 2. Input offset current typ 5 nA (max 200 nA); differential input voltage rating ±16 V.
7 OUT2 output Output of op-amp channel 2. Output swing typ ±14 V (RL>10 kΩ) or ±13 V (RL>2 kΩ) at ±15 V supplies. Short-circuit source/sink currents ~120 mA typical.
8 Vcc power_in Positive supply rail. Absolute maximum ±20 V (i.e., up to 40 V total between Vcc and Vee). PSRR typ 90 dB (RS<10 kΩ).
