Overview

The LM358DT is a versatile, industry-standard dual operational amplifier containing two independent, high-gain, internally frequency-compensated circuits. It is designed to operate from a single power supply over a wide range of voltages from 3V to 30V, or from split supplies. Its input common-mode range includes the negative rail, making it a staple for low-voltage and battery-powered analog signal processing.

Why Choose This Part

The LM358DT offers a balanced combination of 1.1 MHz gain bandwidth and low power consumption of 700uA per channel. It eliminates the need for external compensation components and provides a large output voltage swing that is compatible with most logic families. Its SO-8 package and 2 mV typical input offset voltage provide a reliable, cost-effective solution for standard analog designs.

Applications

Transducer Amplifiers
Ideal for amplifying low-level signals from sensors in single-supply systems where the input needs to sense near ground.
DC Gain Blocks
Used in general-purpose analog circuits requiring a high DC voltage gain of up to 100 dB.
Current Shunt Sensing
Commonly employed in power management circuits to monitor current across a shunt resistor due to its ground-sensing capability.
Active Filters
Suitable for low-frequency filtering and signal conditioning in consumer and industrial electronics.

Getting Started

To evaluate this part, use a standard breadboard with an SOIC-to-DIP adapter or integrate it directly into your PCB layout using the 1.27mm pitch SO-8 footprint. Ensure bypass capacitors of at least 0.1uF are placed close to the VCC pin to minimize noise. For simulation, standard SPICE models for the LM358 family are widely available in most EDA toolchains.
