General Description
consists of two independent, high gain, in-
ternally 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 sys-
tems. For example, the
ated off of the standard +5V power supply voltage which is
used in digital systems and will easily provide the required
interface electronics without requiring the additional
15V
power supplies.
Unique Characteristics
n
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
The unity gain cross frequency is temperature
compensated.
n
The input bias current is also temperature compensated.
Advantages
n
Two internally compensated op amps
n
Eliminates need for dual supplies
n
Allows direct sensing near GND and V
