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

The LM2904WDT: The tape-and-reel (TR) and cut-tape (CT) options suit both prototyping and production reflow; the 8-SOIC body is compatible with standard pick-and-place equipment.

Parametric profile and temperature grade

Dual general-purpose amplifier with a 1.1 MHz gain-bandwidth product and 0.6 V/µs slew rate — adequate for low-frequency signal conditioning, sensor buffering, and active filter stages below 100 kHz. Supply span from 3 V to 30 V single or dual rail, with 700 µA typical quiescent current per amplifier — a balanced trade-off between headroom and power budget for battery-backed or 24 V industrial rails.

Frequently asked questions

How do I get current pricing and availability for LM2904WDT?

Pricing and stock are confirmed at quote time. Submit an RFQ for the LM2904WDT; availability is verified against current independent-distribution inventory.

When sourcing LM2904WDT, what's the closest functional second-source — LM2904WYPT?

The LM2904WYPT is the automotive-grade (AEC-Q100) sibling with identical 1.1 MHz gain-bandwidth, 0.6 V/µs slew rate, and 8-SOIC package. It is a drop-in replacement for the LM2904WDT in designs requiring automotive qualification.
