LM358N: ( For rotation circuitry in Real Flat models )
16.17.1.
General Description
The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers
which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from
split power supplies is also possible and the low power supply current 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 now can be more easily implemented in single power supply systems. For example, the LM158 series can be
directly operated off of the st5V power supply voltage, which is used in digital systems and will easily provide
the required interface electronics without requiring the additional
± 15V power supplies.
16.17.2.
Unique Characteristics
In the 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.
The unity gain cross frequency is temperature compensated.
The input bias current is also temperature compensated.
