**ROHM** · Operational Amplifier · MSOP-8

BA2904FVM-TR from ROHM, in a MSOP-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. Class-AB output stage, VOH >= 3.5V with RL=2kΩ, source current typ 30mA, sink current typ 20mA. |
| 2 | -IN1 | input | Channel 1 inverting input. Input bias current typ 20nA (flowing out of pin, PNP input stage). Common-mode range VEE-0.3V to VEE+36V. |
| 3 | +IN1 | input | Channel 1 non-inverting input. Ground-sense capable; operates down to VEE. Input offset voltage 7mV max. |
| 4 | VEE | power_in | Negative supply / ground pin. Typically tied to GND for single-supply operation. VCC-VEE absolute maximum +36V. |
| 5 | +IN2 | input | Channel 2 non-inverting input. Ground-sense capable; operates down to VEE. Input offset voltage 7mV max. |
| 6 | -IN2 | input | Channel 2 inverting input. Input bias current typ 20nA (flowing out of pin, PNP input stage). |
| 7 | OUT2 | output | Channel 2 op-amp output. Class-AB output stage, source current typ 30mA, sink current typ 20mA. |
| 8 | VCC | power_in | Positive supply pin. Single-supply operation +3.0V to +36.0V (absolute max VCC-VEE = +36V). Supply current typ 0.5mA (both channels). |
