Product details

AEC-Q100 qualified dual op-amp for automotive signal chains

The 1.1 MHz gain-bandwidth product and 0.6 V/µs slew rate are adequate for sensor conditioning, actuator drive, and low-speed filtering in 12 V and 24 V vehicle electrical systems. Supply span from 3 V to 30 V allows direct rail connection in both 5 V logic and 24 V truck/industrial buses without an extra regulator. Each of the two channels draws 700 µA supply current, keeping the total quiescent load under 1.4 mA — a practical fit for always-on ECU modules where standby budget is tight.

Package and footprint — 8-MiniSO (MSOP-8)

The LM258AST is supplied in an 8-lead MiniSO package (also referred to as 8-TSSOP or 8-MSOP with 0.118" body width, 3.00 mm). This is a surface-mount footprint compatible with standard MSOP-8 land patterns.

Frequently asked questions

Is LM258AST suitable for automotive applications?

Yes. This covers passenger-cabin and many under-hood sensor interface applications.

Can LM258AST replace LM358?

The LM258AST is functionally similar to the industry-standard LM358 dual op-amp — same general-purpose amplifier type, dual channels, and wide supply range. However, the LM258AST is AEC-Q100 qualified and specified over -40°C to 105°C, while many LM358 variants are commercial or industrial grade. Pin compatibility depends on the specific package; the LM258AST comes in an 8-MiniSO footprint, not the traditional SOIC-8 or DIP-8 of the LM358. Verify the PCB land pattern before substitution.
