description
These devices consist of two independent, high-gain, frequency-compensated operational amplifiers designed
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 30 V (3 V to 26 V for the LM2904 and LM2904Q), and V
CC
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,
these devices can be operated directly from the standard 5-V supply used in digital systems and easily provides
the required interface electronics without additional ±5-V supplies.
The LM2904Q is manufactured to demanding automotive requirements.
The LM158 and LM158A are characterized for operation over the full military temperature range of –55°C to
125°C. The LM258 and LM258A are characterized for operation from –25°C to 85°C, the LM358 and LM358A
from 0°C to 70°C, and the LM2904 and LM2904Q from –40°C to 125°C.
