Overview
The LM358 IC consists of two independent, high-gain, internally frequency-compensated operational amplifiers. It is widely used because it can operate from a single power supply (e.g., 5V and GND), eliminating the need for dual supplies like +15V/−15V required by older op-amps. This makes it ideal for battery-powered applications such as robotics, embedded systems, and IoT prototypes.
Key Features
- Dual Channel: Two independent op-amps in a single 8-pin package.
- Wide Voltage Range: Operates from 3V to 32V (single supply) or ±1.5V to ±16V (dual supply).
- Low Input Bias Current: Suitable for precision sensing applications.
- High DC Gain: Approximately 100 dB, enabling amplification of very small signals.
- Breadboard Friendly: Standard DIP-8 package for easy prototyping.
