Product details

AEC-Q100 qualified for under-hood analog conditioning

Gain-bandwidth product sits at 1.2 MHz with a slew rate of 0.5 V/µs. That is enough bandwidth to condition signals from thermocouples, pressure sensors, and hall-effect current transducers running at a few hundred kilohertz. Supply current is 700 µA per amplifier — low enough to keep the module's always-on rail within budget, though not a micropower part.

Package and footprint for production assembly

The LM2904BYST is supplied in an 8-lead MiniSO package — surface-mount only.

Frequently asked questions

Is LM2904BYST suitable for automotive applications?

Yes. The LM2904BYST is qualified to AEC-Q100 and rated for an operating temperature range of -40°C to 125°C, which covers the automotive grade-1 requirement for under-hood and cabin environments. The PPAP documentation expected by OEM auditors is supported by the AEC-Q100 qualification status.

Can LM2904BYST replace LM358?

The LM2904BYST is a pin-compatible functional upgrade for the classic LM358 in many circuits, provided the supply voltage stays within 3 V to 36 V and the application requires automotive qualification. Key differences: the LM2904BYST is AEC-Q100 qualified and specified to 125°C, whereas the LM358 is typically commercial/industrial grade. Verify the input offset voltage (4 mV max,) and output current capability (32 mA,) against your design margins.
