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

What this dual op-amp brings to an automotive BOM

The STMicroelectronics LM2904WHYST is a dual general-purpose operational amplifier qualified to AEC-Q100, meaning it is built and tested for automotive-grade reliability — under-hood, cabin, or chassis-domain. The 1.1 MHz gain-bandwidth product and 0.6 V/µs slew rate are typical for a general-purpose op-amp used in sensor signal conditioning, actuator drive, or power-supply feedback loops — not a high-speed part, but adequate for DC to low-kHz analog paths. Supply range spans 3 V to 30 V single supply, which lets it run from a 5 V rail or a 24 V truck battery without a separate regulator.

Supply current and output drive — fitting the rail budget

Each amplifier draws 700 µA supply current, so the dual-channel part pulls about 1.4 mA total quiescent — a reasonable figure for always-on sensor interfaces in a vehicle. Input bias current is 20 nA typical, which keeps offset errors low when working with high-impedance sensors like thermistors or piezo elements.

Package and footprint — hand-solderable SOIC-8

The LM2904WHYST comes in an 8-SOIC package (3.90 mm body width, 0.154" pitch). It is a surface-mount part, but the 1.27 mm lead pitch is easy to hand-solder with a fine tip — no hot-air gun required for prototyping.

The part is ROHS3 compliant.

Frequently asked questions

Is LM2904WHYST AEC-Q100 qualified?

Yes, the LM2904WHYST is AEC-Q100 qualified, making it suitable for automotive applications.

What is the supply current of LM2904WHYST?

The supply current per amplifier is 700 µA, so the dual-channel device draws approximately 1.4 mA total quiescent current.

What is a replacement or equivalent for LM2904WHYST?

A close functional peer is the LM258AWDT from the same STMicroelectronics family, which shares the same 1.1 MHz GBP, 0.6 V/µs slew rate, and dual-channel configuration, but its temperature range tops out at 105°C instead of 150°C. For a wider bandwidth alternative, the TS922IYPT offers 4 MHz GBP and rail-to-rail output, also AEC-Q100 qualified, but draws 2 mA per channel.
