Product details

AEC-Q100 dual op-amp for the harsh-environment BOM

It delivers a 500 kHz gain-bandwidth product and a 0.2 V/µs slew rate from a supply span of 3 V to 36 V, all in an 8-SOP surface-mount package.

The 500 kHz gain-bandwidth and 0.2 V/µs slew rate tell you this is a general-purpose amplifier, not a high-speed signal-chain part. It handles sensor buffering, actuator drive loops, and level translation in automotive ECUs where the signal bandwidth stays below a few tens of kilohertz. The 2 mV input offset and 20 nA input bias are adequate for the 12 V and 24 V system monitoring that dominates automotive analog — you're not chasing microvolt-level transducer signals with this part. The push-pull output stage means it swings rail-to-rail on the output side, though the input common-mode range does not reach the positive rail — keep that in mind if you're doing high-side current sensing at 3.3 V single supply.

It is ROHS3 compliant. No LTB window to navigate, no scavenger-hunt sourcing required. This is a straightforward BOM line to qualify for production.

Housed in an 8-SOP package (the ROHM designation for a standard 8-pin SOIC with 4.40 mm body width). The supplier device package is 8-SOP, which matches the 8-SOIC footprint you already have in your library for similar automotive op-amps.

Frequently asked questions

What is the closest functional second-source for BA82904YF-CE2?

The BA2904YF-MGE2 is the closest functional peer — same AEC-Q100 qualification, same 500 kHz GBW, same 0.2 V/µs slew rate, same 2 mV input offset, same 20 nA input bias, same 30 mA output per channel, same supply range, same package. The difference is the BA2904YF-MGE2 is a 4-circuit device, not a dual. For a dual-channel replacement, the BA2902YF-CE2 shares all the same parametric ratings but is also a quad. No exact pin-compatible dual substitute exists in the family — verify the circuit count before swapping.

Is BA82904YF-CE2 AEC-Q100 qualified?

Yes. It is part of ROHM's Automotive, AEC-Q100 series, which means it has passed the automotive reliability stress tests required for deployment in vehicle electronics.
