What this dual op-amp brings to an automotive board
The ROHM BA2904YF-MGE2 is a dual-channel general-purpose operational amplifier qualified to AEC-Q100, making it a fit for automotive electronic modules — engine control, transmission, body controllers, and sensor interface boards that see under-hood temperatures. It operates across a 3 V to 36 V supply span, so it can run from a regulated 5 V rail or directly off a 12 V battery line without a separate pre-regulator. The 500 kHz gain-bandwidth product and 0.2 V/µs slew rate are sufficient for low-speed sensor amplification, active filtering below 50 kHz, and level-shifting tasks where signal bandwidth is modest.
The wide supply span means the same part can serve a 3.3 V sensor front-end and a 24 V industrial input stage, reducing BOM line items across platforms.
Housed in an 8-SOIC (0.173" body width) with the supplier device package listed as 8-SOP, this is a standard surface-mount footprint shared by many dual op-amps.
