BA2903YF-CE2 from ROHM Semicon, in a SOP-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 | OUT1 | output | Output of comparator channel 1, referenced to the VEE rail and operating within the supply range of +2.0V to +36V (VCC-VEE). |
| 2 | -IN1 | input | Inverting input of comparator channel 1; input voltages below VEE-0.6V cause excessive input current, so a limiting resistor is recommended (absolute maximum input current Ii is -10 mA). |
| 3 | +IN1 | input | Non-inverting input of comparator channel 1; common-mode input range includes ground level, and the absolute maximum common-mode range is (VEE-0.3)V to (VEE+36)V. |
| 4 | VEE | power_in | Negative supply pin; all input and absolute maximum voltage limits are referenced to VEE, and it serves as the ground reference for single-supply operation. |
| 5 | +IN2 | input | Non-inverting input of comparator channel 2; common-mode input range includes ground level, and the absolute maximum common-mode range is (VEE-0.3)V to (VEE+36)V. |
| 6 | -IN2 | input | Inverting input of comparator channel 2; input voltages below VEE-0.6V cause excessive input current, so a limiting resistor is recommended (absolute maximum input current Ii is -10 mA). |
| 7 | OUT2 | output | Output of comparator channel 2, referenced to the VEE rail and operating within the supply range of +2.0V to +36V (VCC-VEE). |
| 8 | VCC | power_in | Positive supply pin; operating supply is +2.0V to +36V in single-supply use or ±1.0V to ±18V in split-supply use, with VCC-VEE absolute maximum of +36V. |
