Overview
The LM358M, produced by Texas Instruments, is a dual operational amplifier designed to operate from a single power supply over a wide range of voltages. It is part of the LM158 series, which includes two independent, high-gain, internally frequency-compensated operational amplifiers. These amplifiers are specifically designed to operate from a single power supply, eliminating the need for dual supplies, and are suitable for various applications including transducer amplifiers, DC gain blocks, and general signal conditioning and amplification.
