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.
NC – No internal connection
Operation from split supplies is also possible
symbol (each amplifier)
when the difference between the two supplies is
3 V to 30 V (for the LM2902 and LM2902Q, 3 V to
26 V) and V_CC is at least 1.5 V more positive than
IN –
the input common-mode voltage. The low supply
OUT
current drain is independent of the magnitude of
IN +
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 ± 15-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 – 55°C to
125°C. The LM224 and LM224A are characterized for operation from – 25°C to 85°C. The LM324 and LM324A
are characterized for operation from 0°C to 70°C. The LM2902 and LM2902Q are characterized for operation
from – 40°C to 125°C.
