LM358 Datasheet: Applications for Low Power Operational Amplifiers
Every engineer remembers the classic LM op-amp from their electronics lab classes. Looking for an op-amp for your next system? Every engineer is likely familiar with the LM and the specifications in the LM datasheet. This common op-amp has plenty of uses in DC and low-frequency AC applications. There are many other op-amps that provide similar specifications, but more advanced applications require an op-amp with larger gain-bandwidth product, common-mode noise rejection, power supply noise rejection, and other specifications.
Here are some of the common variants of the LM and some suitable replacement op-amp components for your analog system. Every electrical engineer is likely familiar with the DIP package footprint for an LM, but LM variants are also available as surface-mount components with gullwing or flat package mounting styles. This gives designers a range of form factor options for DC and analog systems. Each manufacturer produces slightly different variants of this component, and each has very similar specifications.
Some of these components have identical pinouts and package sizes to allow for compatibility between different manufacturers. Here is a short summary of the important LM specifications:.
Other specifications can span broad ranges, and designers should consult their LM datasheet. Although the LM is extremely common and most engineers are familiar with its limits, there are plenty of other op-amps you can use for different applications.
If you need to use an LM, but you want a different number of channels, you can use the LM single-channel or LM quad-channel. The pinouts for common variants of these three components are shown below.
Just like the standard LM, these multi-channel variants also have slight differences in electrical ratings, but they all generally offer the same performance specifications as standard LM op-amps. You can find a great comparison of specifications for some of these op-amps in this document from Rohm. For advanced products that operate in the MHz and GHz regime, the primary specification that needs to change is the gain-bandwidth product.
These components are suitable for RF mobile, satellite, navigation, and weather systems, but going to higher frequencies requires a more specialized amplifier with gain-bandwidth products reaching dozens of GHz. Some of these alternative components are also ideal for low-noise applications and offer CMRR values reaching dB.
Specialized multi-stage amplifiers are available from a number of RF components manufacturers. For radio transmission, GaAs or SiC power amplifiers are normally used as they provide high efficiency up to several GHz.
Working at mmWave frequencies requires GaN-on-SiC amplifiers, particularly in mobile analog front ends. The next task to complete before designing a system around your amplifier is to find CAD and sourcing data for your amplifier.

Dual, 1MHz, Operational Amplifiers for Commercial Industrial, and Military Applications tle A3 al, z, raal pliThe CA, CAA and CA types consist of two independent, high gain, internally frequency compensated operational amplifiers which are designed specifically to operate from a single power supply over a wide range of voltages. They may also be operated from split power supplies. The supply current is basically independent of the supply voltage over the recommended voltage range. These devices are particularly useful in interface circuits with digital systems and can be operated from the single common 5VDC power supply. They are also intended for transducer amplifiers, DC gain blocks and many other conventional op amp circuits which can benefit from the single power supply capability. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
