It is widely used for signal amplification, sensor interfacing, comparator circuits, and active filter design. With its ability to operate from a single supply as low as 3V, it's a popular choice for battery-powered and microcontroller-based projects.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eLM358\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSupply Voltage (Single)\u003c\/td\u003e\n\u003ctd\u003e3V to 32V\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSupply Current per Channel\u003c\/td\u003e\n\u003ctd\u003e0.5 mA (typ.)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput Offset Voltage\u003c\/td\u003e\n\u003ctd\u003e2 mV (max)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003eDIP-8\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-inverting amplifier for boosting weak sensor outputs\u003c\/li\u003e\n  \u003cli\u003eActive low-pass filter for smoothing noisy analog signals\u003c\/li\u003e\n  \u003cli\u003eVoltage comparator with adjustable hysteresis for threshold detection\u003c\/li\u003e\n  \u003cli\u003eAudio preamplifier stage for electret microphones\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe LM358 operates from standard 5V and 3.3V supplies, making it compatible with Arduino, ESP32, Raspberry Pi, and other development boards. It is often used with resistive sensor networks, potentiometers, and capacitor filters. Common pairings include the LM393 comparator or logic-level MOSFETs for driving loads.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect Vcc (pin 8) to +5V and GND (pin 4) to ground. For single-supply operation, bias the non-inverting input to half the supply voltage using a resistive divider. Add a 0.1µF ceramic bypass capacitor across Vcc and GND near the IC. The output can source or sink up to 20mA, so avoid driving heavy loads directly.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
