LM258 / LM358 Dual Op Amps Texas Instruments LM258 and LM358 dual operational amplifiers (op amps) consist of two independent, high-gain frequency-compensated operational amplifiers (op amps) designed to operate from a single supply over a wide range of voltages. The low supply-current drain is independent of the magnitude of the supply voltage. TI LM258 and LM358 op amp applications include transducer amplifiers, DC amplification blocks, and all the conventional op amp circuits that now can be implemented more easily in single-supply-voltage systems.
