Description
The NJM358C / NJM358CA consist of two independent, high-gain, internally frequency-compensated op-amps, specifically designed
to operate from a single power supply over a wide range of voltages. The low-power supply drain is independent of the magnitude of the
power supply voltage.
Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits, which can now be more easily
implemented in single power supply systems. For example, these circuits can be directly supplied with the standard +5V, which is used in
logic systems and will easily provide the required interface electronics with no additional power supply.
In linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though
operated from only a single power supply voltage.

1. Input voltage is the voltage should be allowed to apply to the input terminal independent of the magnitude of VCC+
The normal amplifier operation input voltage is within “Common Mode Input Voltage Range” specified in the Electrical characteristics.
2. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-vase junction of the input PNP transistor
becoming forward-biased and thereby acting as input diode clamp. In addition to this diode action, there is NPN parasitic action on the IC chip. This transistor
action can cause the output voltages of the Op-amps to go to the VCC voltage level (or to ground for a large overdrive) for the time during which an input is
driven negative.
3. Short-circuit can cause excessive heating and destructive dissipation. Values are typical.
