Product Overview

LM358DR is a general-purpose dual operational amplifier launched by Texas Instruments, a core model of the LM358 series. It adopts an SOIC-8 package (Small Outline Integrated Circuit package) and integrates 2 independent, cost-effective operational amplifiers.

With wide voltage range and low quiescent power consumption as its core advantages, this device is designed for signal amplification, voltage comparison, power management and other scenarios. It is widely used in industrial sensors, consumer electronics, automotive electronics and medical equipment, serving as a general op-amp solution that balances performance and cost, meeting the low-power, high-stability signal processing needs of multiple fields.

Key Features

• Ultra-Wide Supply Voltage Range: Supports 2V~32V single-supply or ±1V~±16V dual-supply operation, adapting to power needs from 2V low-power devices to 32V industrial equipment, reducing the difficulty of LM358DR multi-scenario power adaptation;
• Extremely Low Quiescent Power Consumption: Each op-amp has a quiescent current of only 0.7mA (typical), with a total power consumption as low as 1.4mA, significantly extending the battery life of LM358DR low-power devices;
• Industrial-Grade Wide-Temperature Stability: Operating temperature range of -40°C~125°C, withstanding extreme high and low temperature environments, suitable for LM358DR automotive electronics and outdoor industrial equipment scenarios;
• Dual Op-Amp Integrated Design: 2 independent op-amps integrated in a single package, reducing PCB board space occupancy and lowering LM358DR circuit design costs and component procurement complexity;
• High Output Driving Capability: Maximum output current up to 20mA, capable of directly driving LEDs, small relays and other loads without additional driver chips, improving LM358DR circuit integration.

Technical Specifications

Typical Applications

• In industrial sensor signal amplification scenarios, LM358DR relies on its 1MHz bandwidth and 100dB high open-loop gain to accurately amplify weak analog signals (e.g., mV-level signals) output by pressure, temperature and other sensors. The -40°C~125°C wide-temperature design adapts to high and low temperature environments in industrial workshops, while the 2V~32V wide voltage is compatible with different sensor power supply schemes, effectively improving the accuracy and stability of LM358DR industrial signal detection.
• In the field of consumer electronics power management (e.g., power banks, smart speaker power modules), LM358DR can be used as a voltage comparator to monitor power voltage fluctuations and trigger protection mechanisms. The 0.7mA low quiescent power consumption avoids additional power loss, and the SOIC-8 package is compact and suitable for automated placement, adapting to the compact PCB layout of consumer electronics and meeting the needs of LM358DR consumer power protection.
• In automotive electronic auxiliary circuits (e.g., on-board lighting control, tire pressure monitoring modules), the -40°C~125°C wide-temperature range of LM358DR can withstand high temperatures (summer exposure) and low temperatures (winter cold) in vehicles. The 20mA output current can directly drive on-board LED indicators, and the 32V high supply voltage adapts to on-board power fluctuations, ensuring stable operation of LM358DR on-board circuits.
• In medical equipment signal processing scenarios (e.g., portable oximeters, blood pressure monitors), the low input offset voltage (typical 2mV) of LM358DR reduces signal amplification errors, ensuring the accuracy of medical data collection. The 1.4mA total power consumption extends the battery life of the equipment (adapting to portable device needs), while industrial-grade reliability meets the strict stability standards of medical equipment, adapting to LM358DR medical signal amplification needs.
• In smart home control modules (e.g., smart switches, temperature and humidity controllers), LM358DR can realize amplification and comparison of temperature and humidity sensor signals. The 2V low supply voltage adapts to lithium battery power supply, the SOIC-8 package saves PCB space (suitable for small control boxes), and the dual op-amp integrated design can process two signals simultaneously (e.g., temperature + humidity), improving the efficiency of LM358DR smart home control.

Why Choose LM358DR ?

• No Pressure for Multi-Scenario Power Supply: 2V~32V wide voltage range adapts to single/dual power schemes, no need to adjust power supply design for different devices, reducing LM358DR cross-scenario application costs;
• Balance of Low Power Consumption and High Performance: 0.7mA low quiescent power consumption + 1MHz bandwidth, meeting both the battery life needs of low-power devices and ensuring signal processing accuracy, adapting to LM358DR high and low performance scenarios;
• Industrial-Grade Reliability Guarantee: -40°C~125°C wide temperature + original Texas Instruments production, with a failure rate as low as 0.001%/1000 hours (industrial standard), improving the stability of LM358DR high-reliability circuits;
• Integration for Cost and Efficiency Improvement: Dual op-amps in a single package reduce component quantity by 30%, and the SOIC-8 package reduces PCB space occupancy by 25%, balancing LM358DR cost control and design efficiency;
• Strong Load Adaptability: 20mA maximum output current can directly drive small loads without additional driver chips, simplifying the LM358DR circuit design process and shortening the R&D cycle.
