The LM358DR is a dual general-purpose operational amplifier from Texas Instruments (originally ON Semiconductor\/National Semiconductor). It features two independent high-gain internally compensated op-amps designed to operate from a single supply over a wide voltage range (3V to 32V). Packaged in SOIC-8, it is one of the most widely used dual op-amps for signal conditioning, filtering, and buffer applications.<\/p>\n

It operates from a single supply (3V to 32V) or dual supplies (\u00b11.5V to \u00b116V), with a common mode input range that includes ground. With 700 kHz GBW, 100 dB DC gain, and low 0.7 mA per-channel quiescent current, it is the workhorse dual op-amp for general-purpose signal conditioning in consumer and industrial applications.","working_principle":"The LM358DR contains two independent op-amps, each consisting of a differential input stage, gain stage, and output stage. The input stage uses a PNP differential pair that allows the common mode range to extend to ground (VEE), enabling single-supply operation. The gain stage provides the high open-loop gain (100 dB typical), while the internal compensation capacitor (5 pF) ensures stability at unity gain. The output stage is a class AB push-pull that can source and sink current, with short-circuit protection limiting the output current to approximately 40 mA.","pin_description":"\n
