LM358 – dual op amp dip-8

The LM358 is a dual operational amplifier (op-amp) IC with two op-amps in a single package, designed to operate from a single power supply. It is a low-power, general-purpose op-amp commonly used for applications like amplifiers, active filters, and compactors. It can operate over a wide range of supply voltages (3V to 32V), has internal frequency compensation, and its input common-mode range includes ground.

• • Dual op-amp: Contains two independent, high-gain op-amps in one package.
  • Wide voltage range: Can operate from a single power supply with voltages from 3V to 32V, or dual supplies from ±1.5V to ±16V.
  • Low power consumption: Features low supply current that is largely independent of the supply voltage, typically

  • Internal frequency compensation: Simplifies circuit design as it does not require external compensation.
  • Ground-referenced operation: The input common-mode voltage range includes ground, allowing it to sense signals near zero volts, even from a single power supply.
  • High gain: Offers a large DC voltage gain of
