LM358DR Introduction

LM358DR is a dual operational amplifier produced by Texas Instruments, which is widely used in analog signal processing applications. It belongs to the LM358 series and has a "DR" suffix, indicating that its package is SOIC-8 (Small Outline Integrated Circuit 8-pin package), which is suitable for surface mount technology (SMT). The LM358 series operational amplifiers have the characteristics of low power consumption and low cost, suitable for battery-powered devices and various general-purpose operational amplifier applications.

Main features of LM358DR:

Dual-channel operational amplifier:LM358 contains two independent high-gain operational amplifiers that can operate under single or dual power supply.

Low power consumption:The quiescent current of this chip is as low as 0.7 mA, so it is very suitable for battery-powered devices.

Wide power supply voltage range:Supports single power supply (3V to 32V) or dual power supply (±1.5V to ±16V), which can flexibly adapt to different power supply configurations.

High input impedance and low output impedance:The input impedance is high and the output impedance is low, which is suitable for processing high impedance signal sources.

Input voltage range:The input voltage can reach the negative end of the power supply (i.e. 0V), which is suitable for single power supply applications.

Output range:The output voltage range is close to the negative end of the power supply (ground), but cannot completely reach the positive power supply.

Operating temperature range:The typical industrial temperature range is -40°C to 85°C.

LM358DR typical applications:

Signal amplification: Suitable for various low-frequency signal amplification applications, such as sensor signal conditioning, audio amplification, etc.

Filter circuit: It can be used to build low-pass, band-pass, and high-pass filters.

Comparator: Although it is an operational amplifier, it can be used for simple voltage comparison tasks.

Integral and differential circuits: Used for analog calculations and signal processing.

Power management: Suitable for use as an error amplifier in a voltage regulation circuit.

LM358DR and LM358DRG4 are ideal for modern, lead-free, environmentally-compliant designs. The LM358D offers the same functionality but is not lead-free, making it less suited for newer standards.

The LM258DRG4 is a similar part with slightly higher input offset voltage and input bias current, but it is also lead-free and RoHS compliant.

For surface-mount applications with compliance to modern environmental standards, the LM358DR, LM358DRG4, and LM258DRG4 are preferable. The LM358D is still suitable for older designs or through-hole applications but lacks the environmental compliance of the other variants.
