Circuit Principle and Functionality

The LM358 DT contains two independent op-amps, each having a non-inverting input, inverting input, and output. These op-amps are commonly used in signal conditioning, filtering, amplification, and other analog circuit applications. The internal circuitry is compensated for gain, making it stable in most conditions. The op-amps require a dual power supply for proper operation, one positive and one negative.
