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

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.
