AEC-Q100 dual op-amp for 125°C automotive signal chains
It operates across a 3 V to 26 V supply span and delivers a 700 kHz gain-bandwidth product with a 0.3 V/µs slew rate — sufficient for sensor conditioning, actuator drive, and analog signal buffering in engine control units, transmission modules, and body electronics.
Supply range and temperature envelope for under-hood fit
The 3 V minimum supply lets it run on a regulated 3.3 V rail or an unregulated 5 V bus; the 26 V maximum covers 12 V and 24 V automotive systems with headroom for load-dump transients. Each channel draws 500 µA typical supply current, keeping the total thermal load under 1 mA for the pair — a meaningful advantage when the PCB is in a sealed ECU with limited airflow.
For dual-source resilience, the base LM2904 family has multiple qualified sources, though the Q1 suffix specifically gates the AEC-Q100 qualification that automotive lines require.
