AEC-Q100 automotive op-amp — what the grade buys you
The STMicroelectronics LM358ST is a general-purpose dual operational amplifier qualified to AEC-Q100, with an Automotive grade designation. Supply span from 3 V to 30 V covers both the cold-crank dip and the load-dump transient on a 12 V automotive rail without needing a separate regulator. Input bias current is 20 nA typical, and input offset voltage is 2 mV typical — both within the expected spread for a general-purpose bipolar input stage.
NRND — plan your BOM transition
This is not an immediate EOL — the part remains available for existing production programs — but the manufacturer has flagged it for eventual phase-out. For a new automotive ECU or module design, the OEM auditor will expect to see a qualified alternate on the AVL before the PPAP submission.
Package and mounting — 8-MiniSO footprint details
The LM358ST is supplied in an 8-MiniSO package (ST's designation for an 8-lead TSSOP/MSOP with 0.118-inch body width, 3.00 mm nominal width). The supplier device package field lists 8-MiniSO.
Second-source and cross-shopping — LM258AWDT as the nearest alternate
The closest functional match among the listed peers is the LM258AWDT, which shares the same 0.6 V/µs slew rate, 20 nA input bias current, and 700 µA supply current per channel. The LM258AWDT offers a wider gain-bandwidth product of 1.1 MHz (versus 800 kHz) and a wider operating temperature range of -40°C to 105°C (versus 0°C to 70°C). It is also AEC-Q100 qualified and comes in a similar surface-mount package. For a new design that needs the wider temperature range and higher GBW, the LM258AWDT is the natural pin-compatible upgrade, though the pinout should be verified against the specific package variant. The TS922IYPT is a rail-to-rail output device with 4 MHz GBW, better suited for high-speed or single-supply rail-sensing applications, but its 2 mA supply current is higher.
