The LM358DG from STMicroelectronics is a dual general-purpose operational amplifier in an 8-SOIC package. It is part of the industry-standard LM358 family, one of the most widely used op-amps in embedded design. Operating from 3V to 32V single supply or +/-1.5V to +/-16V dual supply, it features an input common-mode range that includes ground, eliminating the need for a negative supply in single-supply applications. With 1.1MHz gain-bandwidth product and 0.6V/us slew rate, it handles audio-frequency signal conditioning, active filtering, and sensor interface amplification. The 300uA per-amplifier supply current suits battery-powered applications.

The LM358DG consists of two independent high-gain internally-compensated operational amplifiers. Each amplifier uses a PNP differential input stage with a Darlington-connected active load, providing an input common-mode range that extends to ground. The gain stage provides the open-loop voltage gain (typically 100dB), and the output stage is a Class AB push-pull capable of sinking 30mA. Internal compensation (a dominant pole at approximately 10Hz) ensures stability in unity-gain configurations without external components. The output can swing to within 1.5V of the positive rail and down to ground (when sinking current), making it suitable for single-supply operation.
