Product details

The supply span from 3 V to 36 V covers both 12 V passenger-car and 24 V truck electrical systems without requiring a separate regulator. Each of the two channels draws 300 µA typical supply current, which keeps the quiescent load low for always-on electronic control units.

Input offset and bias — what to budget in production

For a production design, these are the limits to use in worst-case error budgeting rather than relying on typical values. In a high-gain sensor amplifier, the 1 mV offset translates to a DC error at the output that must be accounted for in the system calibration routine or trimmed during end-of-line test. For loads above 30 mA, buffer the output with a transistor stage.

Package and footprint — 8-TSSOP

The 0.65 mm pin pitch is standard for this package family; verify the land pattern against the IPC-7351B nominal footprint before layout. No exposed thermal pad — junction-to-ambient thermal resistance is managed through the PCB copper area.

It is ROHS3 compliant.

Frequently asked questions

Is LM2904BQPWRQ1 RoHS compliant?

Yes, the part is ROHS3 compliant per the manufacturer's listing.

What is the difference between LM2904 and LM358?

The LM2904BQPWRQ1 is the automotive-grade variant of the commercial LM358. The key differences are AEC-Q100 qualification and the extended -40°C to 125°C temperature range versus the LM358's typical 0°C to 70°C range. Electrical specifications such as 1.2 MHz gain-bandwidth and 0.5 V/µs slew rate are similar between the two families.
