description/ordering information
these devices consist of four independent
high-gain frequency-compensated operational
amplifiers that are designed specifically to operate
from a single supply over a wide range of voltages.
operation from split supplies also is possible if the
difference between the two supplies is 3 v to 32 v
(3 v to 26 v for the lm2902), and vcc is at least
1.5 v more positive than the input common-mode
voltage. the low supply-current drain is
independent of the magnitude of the supply
voltage.
applications include transducer amplifiers, dc amplification blocks, and all the conventional
operational-amplifier circuits that now can be more easily implemented in single-supply-voltage systems. for
example, the lm124 can be operated directly from the standard 5-v supply that is used in digital systems and
provides the required interface electronics, without requiring additional ±15-v supplies.
