LM358DR SMD Dual Operational Amplifiers SOIC-8
The LM358DR is a compact, industry-standard SOIC-8 packaged dual operational amplifier designed for use in single-supply and split-supply systems. Packaged for surface-mount assembly, the device integrates two independent, high-gain, frequency-compensated amplifiers in one small footprint, making it convenient for space-constrained PCBs where two op-amps are required.
Engineered to run from a single supply (and also usable with split supplies), the LM358DR offers stable operation across a broad supply range and maintains low quiescent current per amplifier pair. Its design supports direct sensing near ground because the common-mode input range includes ground, enabling simple interfacing to single-supply digital systems and sensors without extra negative rails.
TI provides the LM358DR as an orderable SOIC-8 part with standard surface-mount mechanical drawings and recommended PCB land patterns; tape-and-reel and other orderable packing details are listed in the datasheet for production assembly. The device’s long history and broad documentation make it a common choice for general-purpose analog signal conditioning in consumer and industrial products.
Features:
- Two independent, internally frequency-compensated op amps in one SOIC-8 package.
- Operates from single or dual supplies (flexible supply usage).
- Common-mode input range includes ground (suitable for single-supply, near-ground sensing).
- Low supply-current drain (small quiescent current for the pair).
- Unity-gain stable (frequency compensated for stable closed-loop operation).
