Footprint Match 100%
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

What this part is and where it fits

The STMicroelectronics LM2904WYDT is a dual-channel, general-purpose operational amplifier qualified to AEC-Q100 for automotive applications. It delivers a gain-bandwidth product of 1.1 MHz with a 0.6 V/µs slew rate, running from a single or split supply spanning 3 V to 30 V. The part is specified over the full automotive temperature range of -40°C to 125°C.

Package and mounting

Housed in an 8-SOIC package (3.90 mm body width), surface-mount only. The Tape & Reel and Cut Tape options suit both prototype assembly and production reflow. No through-hole variant exists for this order code.

Lifecycle and sourcing posture

The LM2904WYDT is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect.
