DESCRIPTION LM358,A 0C, +70C * * These circuits consist of two independent, high gain, Example : LM258N internally frequency compensated which were designed specifically to operate trom a single power . supply over a wide range of voltages. The low power PIN CONNECTIONS (top view) supply drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, dc { TI | 8 gain blocks and all the conventional op-amp circuits which now can be more easily implementedin single 2 CH: rT] 7 power supply systems. For example, these circuits can be directly supplied with the standard + 5V sO 15V. The maximum output current is approximatively 40mA independent of the magnitude of Vcc. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. 3. Vo = 1.4V, Rg = 02, BV < Veo < 30V, 0 < Vic < Voc 1.5V. 4. The direction of the input current is out of the IC. This currant is essentially constant, independent of the state of the output so no loading change exists on the input lines. 5. Due to the proximity of external components insure that coupling is not originating via stray capacitance between these external parts. This typically can be detected as this type of capacitance increases at higher frequences. 6. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode vollaga range is Vcc 1.5V. But either or both inputs can go to +32V without damage.
