LM358DR

LM358DR Description

The LM358DR from Texas Instruments is a general-purpose dual operational amplifier housed in an 8-SOIC surface-mount package, supplied in Tape & Reel (TR) for automated assembly. Designed for low-power, wide-voltage applications, it operates from 3V to 30V, making it versatile for both single and dual-supply configurations. With a 700 kHz gain bandwidth product and 0.3V/µs slew rate, it balances performance and efficiency, ideal for signal conditioning, filtering, and DC amplification. Its low input bias current (20 nA) and 3 mV input offset voltage ensure precision in sensitive circuits.

LM358DR Features

• Dual-channel design: Two independent op-amps in one package, reducing board space.
• Wide supply range (3V–30V): Suitable for battery-powered and industrial systems.
• Low power consumption: 500µA per channel quiescent current extends battery life.
• High output drive (40 mA/channel): Capable of driving relays, LEDs, and small loads directly.
• Robust reliability: ROHS3 compliant, REACH unaffected, and MSL 1 (unlimited) for long-term usability.
• Stable performance: Operates across 0°C to 70°C with minimal drift.

LM358DR Applications

• Sensor interfaces: Amplifies weak signals from thermocouples, strain gauges, or photodiodes.
• Active filters: Low-pass, high-pass, and band-pass designs due to its 700 kHz bandwidth.
• Power management: Voltage regulators/comparators in portable devices.
• Industrial control: Signal buffering in PLCs, motor controllers, and instrumentation.
• Consumer electronics: Audio preamps, tone controls, and LED drivers.

Conclusion of LM358DR

The LM358DR excels in cost-sensitive, space-constrained designs requiring dual op-amps with wide voltage tolerance. Its low noise, high output drive, and reliability make it a preferred choice for industrial, automotive, and consumer applications. Compared to similar models, it offers better power efficiency and broader operating conditions, ensuring consistent performance in diverse environments. A staple in linear IC design, it balances functionality, durability, and affordability.
