The LM358 is an operational amplifier.
YES
In LM358, "LM" stands for "Linear Monolithic." The LM358 is a dual operational amplifier designed for various linear applications. It features a low input offset voltage and operates on a wide range of supply voltages, making it suitable for many analog signal processing tasks.
The LT1013 is a precision JFET-input operational amplifier, and its equivalent can be considered the TL071, which also features a JFET input. The LMC662, a dual op-amp with low power consumption, can be compared to the LM358, although the LM358 is not a low-power op-amp. For precise applications, the OPA2134 may also serve as a modern equivalent to either due to its high performance and low distortion characteristics.
The LM158 series consists 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.For more details, hqew.net is a good place.
In the context of operational amplifiers (op-amps), "LM" typically refers to a series of op-amps produced by Texas Instruments, such as the LM741, LM358, and LM324. These devices are known for their versatility and reliability in various applications, including amplification, filtering, and signal processing. The "LM" designation often indicates that the op-amp is designed for low to moderate power consumption and can operate over a range of supply voltages.
