s LARGE OUTPUT VOLTAGE SWING 0V TO
(VCC - 1.5V)
s ESD INTERNAL PROTECTION : 2kV
DESCRIPTION
This circuit consists of two independent, high gain,
internally frequency compensated which were de-
signed specifically for automotive and industrial
control system. It operates from a single power
supply over a wide range of voltages. The low
power supply drain is independent of the magni-
tude 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 implement-
ed in single power supply ssystems. For example,
these circuits can be directly supplied with off the
standard +5V which is used in logic systems and
will easily provide the required interface electron-
ics without requiring any additional power supply.
In the linear mode the input common-mode volt-
age range includes ground and the output voltage
can also swing to groung, even though operated
from only a single power supply voltage.
