产品概览
The LM358AM from Texas Instruments is a dual general-purpose operational amplifier featuring low power consumption, wide supply voltage range, and unity-gain compensation. It consists of two independent, high-gain, internally frequency-compensated op-amps designed to operate from a single supply over a range of 3V to 32V (or split supplies of +/-1.5V to +/-16V). The ‘M’ suffix indicates the SOIC-8 surface-mount package, suitable for automated PCB assembly.
