It shares all the LM324's key advantages: single-supply operation from 3V to 32V, input common-mode range including ground, output swinging to near ground, and low 350\u00b5A total supply current. The 8-pin DIP footprint is smaller than the LM324's 14-pin, making the LM358 ideal when only one or two op-amp channels are needed. The pinout follows the industry-standard dual-op-amp convention (same as NE5532, TL072, LM833), allowing easy upgrades to higher-performance op-amps. The 1MHz GBW and 0.5V\/\u00b5s slew rate are adequate for DC signal conditioning, audio preamplification, and low-frequency active filtering. At $0.20\/1ku, the LM358 is one of the most cost-effective op-amps available. The N suffix denotes the PDIP-8 through-hole package.","working_principle":"The LM358N operates identically to half of the LM324. Each op-amp uses a PNP differential input stage that allows the common-mode range to include ground. The class AB output stage can source current (pulling output toward V+) and sink current (pulling output toward ground), with the output able to swing to within ~5mV of ground when sinking small currents. In single-supply operation, the signal must remain between 0V and V+\u22121.5V at both input and output. The internal compensation capacitor ensures stability in voltage-follower (unity gain) configuration without external components. Closed-loop bandwidth = GBW \/ noise_gain; at gain=10, BW \u2248 100kHz. The 0.5V\/\u00b5s slew rate limits the full-power bandwidth: at 5V peak output, BW_max = 0.5\/(2\u03c0\u00d75) \u2248 16kHz. For AC-coupled applications, a V+\/2 bias voltage is needed; for DC ground-referenced signals (sensors, battery monitors), no bias is required.","pin_description":"\n

      LM358N uses the PDIP-8 (N) package with industry-standard dual op-amp pinout: Pin 1 = Output A, Pin 2 = Inverting Input A (-), Pin 3 = Non-inverting Input A (+), Pin 4 = GND\/VEE, Pin 5 = Non-inverting Input B (+), Pin 6 = Inverting Input B (-), Pin 7 = Output B, Pin 8 = VCC. This pinout is shared by all dual op-amps in DIP-8 including LM358, LM2904, RC4558, NE5532, and TL072. The single-supply operation (3V-32V or \u00b11.5V to \u00b116V) allows inputs to go to ground without phase reversal. Output swings to within 0-20mV of ground in single-supply configuration. For surface-mount, LM358DR (SOIC-8) provides identical pinout.<\/p>","application_scenarios":"
