LM358 SMD IC – Dual Operational Amplifier 3 V-32 V Single Supply in SMD Package

Description

The LM358 SMD IC is a highly versatile dual operational amplifier, optimized for modern surface-mount electronics and ideal for everything from sensor interfaces to power supply monitoring. This chip integrates two independent op-amps in a single compact SMD-compatible package, and supports single-supply operation from as low as 3 V up to about 32 V, making it perfect for both battery-powered and mains-powered designs.

⚙️ Key Features

• Operates from 3.0 V to 32 V in single-supply mode, and ±1.5 V to ±16 V in dual-supply mode.

• Very low supply current drain (e.g., ~500 µA typical per amplifier) – excellent for battery-operated and low-power applications.

• Input common-mode range includes ground (0 V), enabling direct sensing of signals near ground without needing negative supply.

• Output voltage swing can approach the negative supply (ground) in many cases, increasing flexibility in design.

• SMD versions available in small packages (such as SOIC-8, TSSOP, VSSOP) for compact PCB layouts.

🔧 Applications

The LM358 SMD IC is ideal for a wide range of applications:

• Sensor signal conditioning (LDR, thermistor, Hall sensor etc.)

• Audio pre-amplification and filters

• Power supply monitoring, voltage feedback loops, DC-DC converter control

• Battery-powered devices, portable instrumentation, robotics

• General-purpose amplifier circuits and DIY electronics boards
