BA4580RF-E2 from ROHM Semicon, 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	Channel 1 op-amp output. Drives loads down to RL ≥ 2 kΩ with output swing ±13.5 V (typ) on ±15 V supply, output current up to ±50 mA (absolute max).
2	-IN1	input	Channel 1 inverting input. Input bias current typ 100 nA (flows out of pin, PNP input stage). Common-mode range VEE to VEE+36 V (abs max).
3	+IN1	input	Channel 1 non-inverting input. Input bias current typ 100 nA (flows out of pin). Differential input voltage max ±36 V.
4	VEE	power_in	Negative supply rail. Split-supply operating range ±2 V to ±16 V (VCC-VEE max 36 V). Shared by both op-amp channels.
5	+IN2	input	Channel 2 non-inverting input. Input bias current typ 100 nA (flows out of pin, PNP input stage).
6	-IN2	input	Channel 2 inverting input. Input bias current typ 100 nA. Common-mode range VEE to VEE+36 V (abs max).
7	OUT2	output	Channel 2 op-amp output. Slew rate 5 V/µs (typ), gain-bandwidth product 10 MHz. Drives loads down to RL ≥ 2 kΩ.
8	VCC	power_in	Positive supply rail. Split-supply operating range ±2 V to ±16 V (VCC-VEE max 36 V). Supply current typ 6 mA (both channels, no load).
