DESCRIPTION
These circuits consist of two independent,high gain,
internally frequency compensated which were
designed specifically 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 now can 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 without requiring
any additional power supply.
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.

N otes : 1. This input current only exist when the voltage at any of the input leads is driven negative. It is due to the collec-
tor-base junction of the input PNP transistor becoming forward biased and thereby acting as input diode clamps.
In additi on to this diode action, there is also NPN parasitic action on the IC chip. This transistor action can cause
the output voltages of the Op-amps to go to the V CC voltage level (or to ground for a large overdrive) for the time
duration that an input is driven negative.
This is not destructive and normal output will set up again for input voltage higher than –0.3V.
2. Short-circuits from the output to V CC can cause excessive heating if V CC + > 15V. The maximum output current is
approximatively 40mA independent of the magnitude of V CC . Destructive dissipation can result from simultaneous
short-circuits on all amplifiers.
3. V O
V CC + – 1.5V.
4. The direction of the input current is out of the IC. This current 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 voltage range is V CC +
