Both the operational amplifiers of the IC have very low current consumption and each opamp only consume 1.4mA normally. The input stage of the TL072 contains JFET transistors which insures lower noise as compare to the BJT transistors. The single version (TL071) contains one opamp while the quad version contains four separate operational amplifiers inside due to which the package is different and it contains 14 pins. There are also single and quad version of this IC which are TL071 and TL074. The internal circuitry of IC contains two separate operational amplifiers that can be operated with single or dual supply. TL072 is a very popular operational amplifier IC available in 8 pin dip and other packages. Quiescent current is only 1.4mA to 2.5mA.Dual operational amplifiers in a single package.However, you need to know functions of every pins before it can work better for you.TL072 IC Features / Technical Specifications: LM358 operational amplifier has in total 8 pins. Comparators (Loop control & regulation).DC gain blocks, Digital multimeters, Oscilloscopes.Integrator, Differentiator, Summer, adder, Voltage follower, etc.LM358 amplifier is used in a wide range in circuits, the most common applications: These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant.NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements AEC−Q100 Qualified and PPAP Capable.ESD Clamps on the Inputs Increase Ruggedness of the Device without Affecting Operation.Common Mode Range Extends to Negative Supply.LM358 DatasheetĪccording to LM358 datasheet, it features: The output voltage range also includes the negative power supply voltage. The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications.
The amplifier can operate at supply voltages as low as 3.0 V or as high as 32 V. It has several distinct advantages over standard operational amplifier types in single supply applications. The LM358 opamp features low power drain, a common mode input voltage range extending to ground/VEE, and single supply or split supply operation. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. The LM358 is available in a chip sized package (8-Bump micro SMD) using National’s micro SMD package technology. The LM358 op amp belongs to a sort of low power dual operational amplifiers, consisted of two independent, high gain, internally frequency compensated operational amplifiers, which were designed specifically to operate from a single power supply over a wide range of voltages.
