Supply Chain & Allocation Reality:

The ubiquitous dual op-amp designed in the 1970s. While cheap, legacy bipolar LM358 parts suffer from crossover distortion and output swing limited to V+ - 1.5V. Modern precision drop-in replacements like SGMicro SGM8552 and 3PEAK TP358 deliver rail-to-rail I/O, lower offset voltage, and microamp quiescent power at comparable pricing.

Buyer & Quality Checklist for Sourcing Alternatives
  • Check maximum supply voltage: legacy bipolar LM358 operates up to 32V; if your circuit runs on 12V–24V supply rails, select high-voltage variants (e.g., SGM8272 or TP156) instead of 5.5V rail-to-rail models.
  • Confirm ADC input scaling: rail-to-rail output swings up to VCC - 10mV, allowing higher dynamic measurement resolution for current sense shunts.
Frequently Asked Technical Questions

Q: When should I upgrade from legacy LM358 to SGM8552 or TP358?

A: Upgrade if your system operates on 3.3V or 5V logic rails and feeds an internal microcontroller ADC. Legacy LM358 cannot drive outputs higher than ~1.8V on a 3.3V supply, throwing away nearly half of your ADC conversion resolution. Rail-to-rail alternatives solve this instantly with zero board changes.

Technical Details & Description

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.
