Overview

The LM358DGKR is a dual-channel, general-purpose operational amplifier designed for a wide range of low-power signal conditioning tasks. It operates over a supply range of 5V to 30V and features two independent amplifiers in a compact 8-VSSOP package. This part is a staple in analog design due to its ability to operate from a single power supply while maintaining a low quiescent current of 350uA per channel.

Why Choose This Part

The LM358DGKR offers a highly cost-effective solution for dual-amplifier needs in space-constrained layouts. Its low input bias current of 20 nA and broad supply range make it compatible with various power architectures, from single 5V rails to higher voltage industrial systems.

Applications

Transducer Amplifiers
Interfacing low-voltage sensors with microcontrollers by providing necessary gain and impedance matching.
DC Gain Blocks
Providing simple signal amplification in circuits where high speed and precision are not critical requirements.
Active Filters
Implementing low-pass or high-pass filters for audio or sensor signal smoothing with its 700 kHz bandwidth.
Comparator Functions
Acting as a basic voltage comparator in non-critical monitoring circuits where a dedicated comparator IC is not available.

Getting Started

Engineers can prototype with the LM358DGKR using MSOP-8 to DIP adapters on a breadboard. When designing the PCB, ensure adequate decoupling with a 0.1uF capacitor close to the VCC pin, and note that the output swing is typically limited to VCC-1.5V.
