AS358M / AS358MTR-E1 Dual Op-Amp IC SOP-8 – Pack of 5 (LM358 Compatible)

AS358M / AS358MTR-E1 Dual Op-Amp IC – SOP-8, Pack of 5

The AS358M / AS358MTR-E1 is a dual general-purpose operational amplifier in a compact SOP-8 surface-mount package, functionally compatible with the industry-standard LM358. With single-supply operation from 3V to 32V, input common-mode range extending to ground, and output swing to within millivolts of the negative rail, it's the SMD equivalent of the LM358 – ideal for battery-powered circuits, sensor signal conditioning, and analog processing in PCB designs. This 5-piece SOP-8 pack is ideal for PCB repair and production.

AS358M vs LM358 – SMD Replacement

• AS358M (SOP-8): SMD surface-mount, same electrical specs as LM358, for PCB production and repair
• LM358N (DIP-8): Through-hole, breadboard and through-hole PCB use
• Functionally identical – direct SMD replacement for LM358 in PCB designs
• Same pin configuration – no circuit changes required

Typical Applications

• Sensor signal conditioning: Amplify and buffer analog sensor outputs for ADC input
• Comparator circuits: Voltage threshold detection (use LM393 for dedicated comparator)
• Active filters: Low-pass, high-pass, and bandpass filter stages
• Battery-powered circuits: Single-supply analog processing from 3V–5V
• PCB repair: SMD replacement for failed LM358/AS358 in consumer electronics
• Arduino signal conditioning: Amplify sensor signals before ADC input
