BA2904YF-MGE2

ROHM Semicon · Operational Amplifier · SOP-8

BA2904YF-MGE2 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 the channel 1 operational amplifier.
2 -IN1 input Inverting input of channel 1; the input common-mode voltage range is (VEE-0.3) V to (VEE+36) V per the absolute maximum ratings.
3 +IN1 input Non-inverting input of channel 1; the input common-mode range includes ground and is limited to (VEE-0.3) V to (VEE+36) V.
4 VEE power_in Negative supply pin; operating supply voltage VCC-VEE is +3.0 V to +36 V (single supply) or ±1.5 V to ±18 V (dual supply).
5 +IN2 input Non-inverting input of channel 2; the input common-mode range includes ground and is limited to (VEE-0.3) V to (VEE+36) V.
6 -IN2 input Inverting input of channel 2; the input common-mode voltage range is (VEE-0.3) V to (VEE+36) V per the absolute maximum ratings.
7 OUT2 output Output of the channel 2 operational amplifier.
8 VCC power_in Positive supply pin; absolute maximum supply voltage VCC-VEE is +36 V.
