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
NC − No internal connection
(3 V to 26 V for the LM2902), and V
is at least
CC
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.
