3 Description
This device consists 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 is possible when the difference between
the two supplies is 3 V to 36 V (for B-version devices),
3 V to 32 V (for V-version devices) or 3 V to 26
V (for all other devices), 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 LM2902 can be operated directly
from the standard 5-V supply that is used in
digital systems and easily provides the required
interface electronics without requiring additional ±15-V
supplies.
