Schematic diagrams are as shown as following:įigure 2. Input common-mode voltage maximum VCC about 1.5 V Low consumption current, suitable for battery power supplyĪ range of common-mode input voltages, including groundingĪ range of power supply voltage: single supply (3 to 30V) dual supply (☑.5 to ☑5V)Ī range of differential mode input voltage equal to the range of power supply voltage Large output-voltage swing (0 to Vcc-1.5V) The LM358 has plug-in type and the patch type packaging which are the plastic package with double-row 8 lead wires. Its applying range includes sensor amplifiers, DC gain modules, audio amplifiers, industrial control, DC gain components, and all other situations where operational amplifiers can be used with a single power supply.

Under recommended operating conditions: the power supply current is independent of the power supply voltage. The LM358 includes two independent, high gain, internal-frequency compensated dual operational amplifiers that are suitable for single power sources with a wide range of voltages, as well as dual-power operation modes. This is a tutorial video introducing what's an opearational amplifier in details. This circuit can also be used as an atmospheric pressure detector as well including an exhaust gas detector.This article mainly tells about what's an op amp, and then briefly introduce LM358 about its features and parameters, the last we present you the 24 classical circuits of LM358.

This circuit is being used to detect ventilation in areas such as the car motor, where the fuel consumption of the engine has to be analyzed. This entire circuit is supplied with 12v DC. The consumer can flow air through his mouth, though, too. To wind through the filament, a pushbutton and a DC fan are being used. See more LM358 and op-amp circuits here.įor circuit calibration, a potentiometer is being used.

Op-amp is programmed in emitter mode that contrasts the input’s amplitude to the reference voltage and therefore provides the output. The Op-amp LM358 detects this voltage difference and has a low signal. So, the bulb filament produces a signal gap. The bulb filament’s humidity or wind speed decreases, and the filament intensity improves, like any airflow enters. So if there is no air by design, the bulb filament’s resistance value is low because of some wind.
