BA4580RF-E2

ROHM Semicon · Operational Amplifier · SOP-8

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).
