Description

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 is also possible
when the difference between the two supplies is
3 V to 30 V (for the LM2902 and LM2902Q, 3 V to
26 V) 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 easily provides
the required interface electronics without requiring additional ¡À15-V supplies.
The LM2902Q is manufactured to demanding automotive requirements.
The LM124 and LM124A are characterized for operation over the full military temperature range of ¨C55¡ãC to
125¡ãC. The LM224 and LM224A are characterized for operation from ¨C25¡ãC to 85¡ãC. The LM324 and LM324A
are characterized for operation from 0¡ãC to 70¡ãC. The LM2902 and LM2902Q are characterized for operation
from ¨C40¡ãC to 125¡ãC.
